hunting behavior

self care is coming face to face with a ghost and setting out on a quest to capture what you once saw onto video with no big camera crews following you around joined only by your fellow investigator nick groff and your equipment tech aaron goodwin as you travel to some of the most highly active paranormal locations where you spend an entire night being locked down from dusk till dawn

Across the world and for millions of years, army ant colonies have been infiltrated by impostors—beetles that pass for ants and make their living as parasites. Army ants are named for their aggressive hunting behavior, and they’re also fierce defenders of their colonies. But this hasn’t stopped several beetle species from the family Staphylidae which have evolved to infiltrate roaming army ant colonies and live in them as parasites. A new study published in the journal Current Biology finds this capacity evolved not just once, but at least a dozen times in beetle species that are only distantly related.

"A lost dog poster (up next to a free kittens ad and a for rent sign…)" I'm sorry I don't understand what this means...

Cas. The “dog who thinks he’s people.” The Winchesters’ “attack dog.” Who’s currently “lost.” Because he’s not answering his phone and Dean can’t even track him with his phone’s GPS, and he’s even tried checking through national police databases to see if anyone fitting Cas’s description has been arrested… I mean, Dean was trying to distract himself from the fact that he couldn’t find his dog by going down to the pound to pet a different dog. Basically. Metaphorically speaking.

I think fandom has pretty universally decided that Cas would be a cat person.

And for rent could mean several different things… but mostly the fact that Dean’s waiting for Cas to properly come home, move into the bunker.

What's the protocol for when the power goes out at the aquarium? And do you have advice of what to do to keep fish (and filter bacteria!) alive if the power goes out? :)

Okay, staff at the aquarium actually get questions like this frequently from visitors. This is because visitors are often quite shocked to realize that many of the animals they saw during childhood visits are still there, in spite of Hurricane Sandy and all the damage it brought to the Jersey shore. They start asking about how we weathered the storm.

The truth is, we have major plans in place for handling any emergency or power outage. This is how the aquarium staff (at the time of Sandy, I was still just a volunteer!) did so well. By having plans in place and reviewing them, it greatly helps with most issues.

Minor power outages or rolling brownouts are a common enough occurrence during the worst of summer heatwaves or storms, no matter where you live NJ. While modern upgrades and redundancies to the power grid has removed much of the risk of significant power loss, it can happen.

To deal with minor losses, we have a few hidden treasures tucked away. While the building has emergency lighting to assist with human navigation, every free-standing exhibit has a flashlight or lantern tucked underneath. Why? Well, every extra bit of light is important to help us pathetic humans navigate in the dark. We employees and volunteers know our aquarium and the terrain pretty well, but that doesn’t mean it can’t be hazardous in the dark. This means helping everyone get around safely to a secure area or possibly exiting the building if external conditions warrant is priority 1.

These lights are also crucial for our sharks and their tank mates. Successfully keeping larger sharks with fish requires working with their natural tendencies. Sharks tend to be more active with hunting at night. One of the biggest tricks to keeping sharks in aquaria is making sure they have a nightlight. It need not be bright enough to disturb, just bright enough to prevent them from getting into that hunting behavior and starting to look at their tank mates as a possible snack. So, a big job is specifically ensuring that there are lights on our sharks.

Side note : I picture this whenever we talk about power outages and shining flashlights for the sharks. I’ve never experienced a power outage at work, but I have a feeling this will be me if it happens while I’m around the sharks.

In addition to hidden flashlights, each and every free-standing exhibit has a hidden emergency kit underneath including a battery operated air pump, line, and stone. If the power outage will continue longer than a minor inconvenience, these little battery operated pumps can be set up to keep some circulation and surface disturbance in the exhibits.

This plan for dealing with minor outages is only as good as our prior preparation. So, these pumps and flashlights are frequently checked to ensure that everything is in working order and that they all have good batteries. We have a cache of batteries in our lab, as well as a huge tote of spares.

If a power outage looks like it is going to persist for longer than a few hours, then we have a bit of a challenge on our hands. Temperatures on smaller exhibits (especially terrestrial ectotherms) may begin to slide, and prolonged stagnation of water through filter media may cause the beneficial bacteria to consume all available oxygen (and die). The aquarium has generators on hand for this very emergency. We may not be able to operate ALL life support systems, but our generators can handle ensuring that critical systems are functioning.

Where it gets interesting is our water quality monitoring. In our day to day operations, the aquarium alternates between two systems from Hach and YSI. These are both battery operated, handheld devices with internal lighting that we can use to go from tank to tank and monitor for temperature, dissolved oxygen, salinity, and pH (on the YSI). As we test, the data is displayed on the device in use and is also stored for later retrieval. So, although I need a computer to upload data and make our pretty spreadsheets for logging purposes, I could still easily go around and ensure that each tank is sitting within a reasonable range for general parameters.

Our aquarium has two levels, and our upper level has been known to turn into “tent-city” when a prolonged outage is expected (or a significant storm). Staff has camped out there and spent the night to ensure that nothing goes awry. I am told, however, that the seals make bad roommates (they can be active and noisy at night, apparently!).

We also put in a ton of prep work if we suspect an event will cause us to lose power, such as a hurricane or other major weather event. This may include things like setting up the generators, putting pumps into place, etc. By being ready in advance of the power going out, we’ve already done much of the hard work. I also like to think it gets us in the right mindset for when the power does go out, no different than having a fire drill.

Okay, I think this is long enough for one post. I’m going to make a second one for home hobbyists dealing with power loss.

30 Day Retrosaur Challenge part 17 - Apex Predator

Living during the mid Cretaceous, Praedonius (meaning ‘the pirate’, due to the sail-like ridge running along its back) was a very successful predator due to its versatile hunting behavior. It could surprise its prey in an ambush, chase down and exhaust quarry while running on all fours, and was an adept swimmer, able to chase aquatic and semi-aquatic prey, like Duck-Billed Goliaths. When large prey was scarce, it would resort to foraging for small fry.

It did face stiff competition when other invasive tyrant species moved into its territory. That being said, it did have a mutually beneficial relationship with some True Tyrants, such as Akrodon. For instance, Praedonius would swim behind a herd wading of duck-bills in order to chase them onto the land, where an Akrodon is laying in wait. Or vice versa, with Akrodon chasing them into the lake. By working together, both predators had a higher rate of success while hunting.

The large, leisurely Aragorn insists on “scent-rolling time” prior to every treadmill session. He used to shock the trainers and students with spontaneous “surprise-rolls” while the treadmill was running at full speed. Making it stop before he could get hurt, was quite a challenge, so we decided to allow him this little privilege…

“My cat likes climbing trees!” It’s a good thing cat trees and cat shelves are a thing.

“My cat likes digging!” It’s a good thing you can provide them with a dig box.

“My cat likes hunting!” It’s a good thing there are many, many toys designed to encourage a cat’s natural hunting behavior.

“My cat likes scratching the trees!” It’s a good thing scratching posts are a thing, they even come in as wide of a variety as trees.

“My cat likes the fresh air!” It’s a good thing you can open a screened window for them, or build a catio.

“My cat likes to play with other cats!” It’s a good thing you can get another cat, or harness train them so they can go out and see their friends in a controlled setting.

“My cat doesn’t like using the litter box!” It’s a good thing you can experiment with litter types, box styles, box sizes, and box placement until you find something that sticks.

エンコウノトリ
 番いのふりをして異性を喜ばせるコウノトリ。世界中に生息しており、おそらく、最も起源の古いいきものの一つであると考えられている。一緒にエサを食べる、遊び行為を行う、抜け落ちた毛や抜け殻を渡すなどの行為によって、性欲の旺盛な異性の個体を満足させ、その見返りとしてエサを受け取る。この行為は、エンコウノトリにとっての狩りであり、エサを得るための手段でしかない。よって、相手に対して好意を抱いているというわけではなく、楽しそうに見えたとしても、それは演技であり一種の擬態である。
 性欲は、いきものが有する根源的な欲求の一つである。この衝動を利用してエサを得るいきものは非常に多く、かつ決して絶滅することがない。それだけ生態系にとって必要とされている存在であるにもかかわらず、このようないきものや、それらにエサを渡すいきものを攻撃するものは多い。エンコウノトリもこのようないきものの一種であるが、その中でも特に発生を防ごうとする生態系が多い種として知られている。
 このいきものが問題視されるほど増加した原因として、若いいきものが親に知られることなく多くのいきものとコミュニケーションを取ることが可能になったということが挙げられる。特に、ケータイマダラやカミナリグモの生息域が拡大したことによって、個体数と活動の規模が飛躍的に増加した。これを受けて、多くの生態系ではこれらのいきものの縄張りを縮小しようとしているが、新たないきものの発生は止めることができない。自然界の掟と、進化による遷移が、いたちごっこをしているような状態である。
 エンコウノトリは、通常の狩りができないほどに能力が低い。自分でエサを採れないがゆえに、別のいきものから分けてもらうしかなく、その代わりに差し出せるものは、自分自身以外になかったのである。この能力の低さは、このいきものの若さに起因するものであり、生態の本質もそこにある。自分の意志で変態したにもかかわらず、その原因を誰かになすり付けるという愚かしさも、全ては若さのせいである。
 そして、このいきものはいなくなった方がよい、いるとしたら保護すべきであるという主張の根源も、その若さにある。それこそが、たとえ損をしているものがいなくとも、若いいきものが番いになるべきではないという習慣を形成しているのである。
 その習慣を、自由を縛るものだとして無視し続けたエンコウノトリが、自分で自分に卵を運び、育てられずに捨てている。

Youthful Prostistork
 Youthful Prostistork is storks that pretend to be a couple and delight the other sex. They live all over the world, and are considered that maybe they are one of the most ancient CREATURES. They satisfy individuals with vigorous sexual desire by acts such as eating feeds together, doing play behaviors, passing over fallen out hairs and cast‐off skins. And then, they receive feed in return. This behavior is hunting for the Youthful Prostistorks, and is only a means to get feed. Therefore, they do not have favor with the opponents. Even if they look happy, it is performance, and a kind of mimicry.
 Sexual desire is one of the fundamental desires that CREATURES possess. There are so many CREATURES that use this urge to get feed, and they will never be extinct. Despite the fact that they are required for ecosystems, there are many ones that attack such CREATURES and the CREATURES that hand over feed to them. Youthful Prostistorks are also a kind of such CREATURES, but they are known as species that there are many ecosystems to prevent emerging them, in particular.
 As the reasons why this CREATURES have increased so much as to be problematic, there is that young CREATURES have become possible to communicate with many CREATURES without being known to their parents. In particular, the expansion of the habitats of Celldier Butterflies and Cyber Spiders dramatically increased their number of individuals and scale of activities. In response to this, many ecosystems are trying to reduce the territory of these CREATURES, but the emerging of new CREATURES can not be stopped. The rule of nature and the transition by evolution are in a state that playing a cat‐and‐mouse game.
 Youthful Prostistork’s ability are so low that they can not do normal hunting. They can not hunt feed themselves, so they can only receive it from another CREATURE. And they do not have things that can offer in return, except for only themselves. This low ability is due to this CREATURE’s youthfulness, and their essence of mode of life is also there. The foolishness of forcing the cause to someone despite the fact that they have metamorphosed by their own will, is also due to their youthfulness.
 And the root of the assertion that this CREATURE are better not to emerge, and that they should be protected if they exist, is also in their youthfulness. That is what forms the habit that young CREATURES should not be a couple even if there is nobody losing something.
 The Youthful Prostistorks that kept ignoring this habit by the reason that their freedom is bound by it, is carrying the eggs to themselves, and throwing it away without breeding it.

The Hunt is On- Weekly Nest Notes

E9 has become a great flyer and explorer of the territory. Twists and turns maneuvering through the trees feeling the freedom of soaring have taken E9 to new and exciting places. E9 practices and sharpens lessons learned and inherent skills with each new day. Nature has provided E9 with many of the necessary tools for survival and with great Eagle parents to pave the way for E9’s success. E9 has grown in confidence and courage engaging in hunting and fishing behaviors, skimming the pond flushing out the water fowl swimming there and flying after the other birds constantly buzzing by. E9 works on agility hopping from branch to branch among the trees, picking at the bark, pulling at the leaves and pine needles, losing balance and regaining it to fly off. What may seem like antics and play are actions that build strength and ability as E9 begins to hunt and catch prey.

M15 had a banner day fishing delivering several fish in a short period of time. E9 displayed tremendous ability in preserving the fish stash and even tried to hide some of it from Mom and Dad as they stood by. E9 feasted on the meal to almost bursting. E9 successfully stole a fish from Mom on the pond snag and flew back to the nest with it. Harriet and M15 have provided E9 every opportunity to excel.

Observers of nature are drawn in and find solace in its beauty and peacefulness. Our humanness allows us to make observations with our hearts. We can never know for sure the workings of it all. Possibilities that we can never predict or see happen throughout nature.

As time grows nearer for E9 to embark on the hunt for the greatest adventure of all, we have seen that E9 will fare well as an intelligent and skilled Juvenile Eagle.

Some of the pups learning how to fish today at SeaWorld! They are seriously the best. Can’t wait until the next batch gets released. Seriously the most rewarding job ever.

There’s only a few live fish in there to encourage hunting behaviors because having enough live fish to sustain the entire park while making sure each animal meets its specific diet requirements (each animal is an individual and requires different kcals and nutrients depending on its age, sex, health, etc) would be ridiculously difficult only using live fish. Plus, if only live fish were used, dominant animals would prevent smaller, submissive ones from eating their full diets.

How to teach humans basic hunting? I'm a cat and my human is the most terrible hunter ever. She is interested in birds and watches them fly and hopp around. She even feeds them in winter! She is allowed outside but she never tries to hunt the birds. She keeps a distance. Several meters. Always. And if the bird comes closer she doesn't react correctly. The bird could sit next to her and she'd do nothing! No signs of normal hunting behavior. Help?

Despite all the felinomorphic media you might see in which humans are depicted as “just like us” and “big kittens without fur” you need to remember that they are fully evolved creatures all their own, with a rich evolutionary history. Their needs are not necessarily the same as yours. Resisting the impulse to stereotype every human behavior as if it were just like ours, let’s look at the science:

“Average human kills 3 other mammals a year” factoid actually just statistical error. average human kills 0 other mammals per year. Cowboy Georg, who lives in cave & kills over 10,000 other mammals each day, is an outlier and should not have been counted.

Hey you're pretty cool and you know a lot about dinosaurs so I have a quick question for you! Do you think that carnivorous dinos like velociraptors had slit pupils or circular ones? I'm just curious! Also your webcomic is really cool! (Both of them)

Hello! Thank you for reading my comics :3  While I do know more about dinosaurs than the average bear, I’m certainly only a Junior Paleontologist and you should take my answer with many grains of salt. If any of my followers know more about dino eyes, feel free to answer in greater depth or correct me!

Slit pupils have evolved in unrelated species a number of times, which means they probably serve a specific purpose. Slit pupils tend to be found in small to medium nocturnal creatures, mostly predators but not exclusively! This article by koryos​ about different pupil shapes was really informative– a current prevailing theory is they’re useful in distinguishing colors at night, as well as movement on a horizontal plane. So slit pupils are useful for small to medium sized predators who hunt close to the ground in low light!

In the case of dinosaurs, things like hunting behaviors (and behaviors in general) are kind of tricky to determine. It’s not often that a fossil gives us a perfect snapshot of what the creature was up to in its daily life, but we can look at the shapes of the bones and compare them to modern animals and try to piece it together from there. There was recently a study that looked at the size of the scleral ring, a ring of bones that supports the eye in some vertebrate groups. They reasoned that if the scleral opening was of a certain width in proportion to the rest of the eye, the creature was probably more active at night, as the opening could allow for more light to be let in. It’s not a perfect system, and I think some experts have taken issue with it, but many of today’s predators hunt mostly at night– so I feel it’s not too much of stretch to think the meat-eating dinosaurs preferred the cover of darkness.

So basically, all this is to say that if the dinosaur was small to medium in size and has a large scleral opening, it could have had slit pupils! Velociraptor mongoliensis seems a pretty good candidate, to name just one. But giants like T rex probably didn’t have slit pupils, even if they were night hunters.

But again, I am not actually an expert! And if anyone knows better than I do, please let me know!

AN:  HOW FUCKING DARE YOU DRAG SWANFIRE INTO THIS UNHOLY MESS.

His son was completely hopeless.  There was no doubt about it.  

It wasn’t his fault.  Not really.  His son walked on two legs, had no scales to speak of, spoke in that strange language with no trills or snarls.  Nevertheless, Gold had grown a soft spot for the little tyke, with his absurdly thin skin, lack of claws, no teeth to speak of.  His sisters and brother laughed at the little one, but Gold had snarled at them to keep quiet.  After all, didn’t their Alpha have these traits?  And everyone knew Alpha was wise, kind, smelled of strength and passion.  She was strange-looking, but she was their’s.  His.  

His son would simply have to learn how to be like Alpha.  

Gold noticed his son, flirting with the woman in white.  He wasn’t very good at it.  No mating dance, no songs of love, just a ridiculous head tilt towards the woman in white.  The woman in white was probably attractive, with her golden curls and storm-colored eyes, but she was no Alpha.  Nevertheless, it was Gold’s duty to show his son how to court the woman in white.  

He waited for his moment, when the woman in white, his son, and Alpha stood above them on the bridge.  He approached them all and looked directly at his son, trilling a greeting.  

“That’s Gold,” His son said. “Belle’s favorite. He’s kinda fond of me, I think, sometimes.”  

“His scales are beautiful,” The woman in white remarked. “But look at those scars…”

“He fought long and hard for dominance,” Alpha said proudly. “He’s wonderful.”  There was tenderness in Alpha’s voice, and he preened proudly.  

Bobbing his head, he looked directly at his son.  His son clearly had no idea how to court the woman in white–he was standing right next to her and hadn’t even done a basic mating call!  He trilled beautifully, waiting for his son to repeat.

“Is he challenging you?” The woman in white asked amusedly.  

His son cocked his head.  “I don’t think so. I’ve never heard that call before.”

Alpha chuckled.  “I have…but I’m not sure what he’s getting at.”

Gold exhaled impatiently.  He began a complex dance, one foot in front of the other, trilling towards Alpha.  He waited for his son to follow his lead and snarled grumpily when his actions weren’t repeated.  

“What is he doing?” The woman in white asked in fascination. “That’s not hunting behavior, is it?”

“I have no idea,” His son said perplexed. 

Alpha went crimson.  Gold knew that meant he had pleased his Alpha and crowed in triumph.  At least this afternoon wasn’t a total loss.

  • Someone: I can't keep my cat inside! They get bored and they can't hunt! It's good to ecourage natural behaviors!
