it’s time to talk about weird animals again here at bunjywunjy.tumblr.com, and today our topic is Predatory Tunicates, which are a species of evil sock puppet that lives on the sides of deep sea canyons.

wokka wokka wokka!

they function pretty much exactly like you’d think they would, behaving much like a venus flytrap. 

fish goes in, fish DOES NOT COME OUT

the Predatory Tunicate is also the only tunicate known to be carnivorous. other tunicates are content to drift in the currents like lonely plastic bags, lacking the drive and ambition of the Predatory Tunicate.

role model!

also, like most deep sea creatures, Predatory Tunicates are massively improved by the addition of googly eyes.

it’s a true science fact!

they say that thirty meters down in the ocean, a diver loses his senses, forgets which way is up, and swims deeper and deeper and deeper down. they say it’s like being drunk (or stupid) (or maybe some of each) to get dizzy in a dark place and stay, to forget the thing that’s trying to kill you and follow it.

and i am always thirty meters under. it is always dark and i am always forgetting to breathe, always forgetting that you are the thing to escape from. this is the midnight zone they warned you about, i am too deep in to go back up.

Gulper Eel

Also known as the Pelican Eel, this deep sea creature is rarely seen by humans. The gulper eel has a losely hinged mouth that can be opened wide enough to swallow fish that are even much larger than the eel itself. It’s stomach can also stretch and expand to hold its prey.

What better way to celebrate Cephalopod Week than with a stubby squid? 

Last year, we teamed up with Nautilus Live to explore the deep ocean in and around Channel Islands National Marine Sanctuary, and spotted this little googly-eyed cephalopod! 

Though they look like a cross between an octopus and a squid, stubby squid are actually closely related to cuttlefish. They spend their lives on the seafloor, coating themselves in a mucus jacket and burrowing into the sediment. Leaving just those big eyes peeking above the surface, they remain buried until prey items like shrimp or small fish – or a curious ROV – pass by.

hello on this fine day here at bunjywunjy dot tumblr dot com and it’s time to talk about weird animals again.

today we’re going to learn about that denizen of the deep sea that looks like it’s in on the ultimate cosmic inside-joke, the Snipe Eel.

(no, they won’t explain it)

about five feet long, they live a dreary existence feasting upon shrimp in the lightless dark, like nature’s saddest cocktail party.

at least they get to gloat over the fact that they have more vertebrae than any other creature on earth. we would say we’re impressed but honestly that just sounds really unpleasant. yikes.

that sure is a thing to be proud of and not a reason to pity them even more, no sir.

while the Snipe Eel rarely appears in popular culture, A TRAGEDY BEYOND MEASURE, it is believed to have inspired the Pokemon Gorebyss.

slap some mermaid boobs and a shitty Speed stat on it and call it a day

a final lesson we can take from our friend the snipe eel is that a big smile will get you anywhere in life, as long as it’s coupled with aggressive wiggling

This beautiful juvenile octopus is just 2 centimetres (an inch) wide. It was spotted at night in the deep water off the coast of Tahiti by Fabien Michenet, France, for the “Wildlife Photographer of the Year 2015″ contest.

Its transparent body lets us admire its internal organs. Notice also the orange spots on its tentacles: that’s its chromatophores, i.e. the colour-changing cells used for camouflage.

The Extreme World of Deep Sea Cephalopods

Although it is the home of approximately 98% of the ocean’s species, the deep sea is a frontier yet to be explored by natural scientists. Of the estimated 500.000 to 10 million species living on or above the seafloor, new species are discovered and described by marine biologists every year. Being one of the biggest and most extreme environments on Earth, the deep sea’s biodiversity is enormous in both species of prey and predators. From demonic red octopi to gigantic squid wrestling with sperm whales, the most interesting group of marine predators would be the deep sea’s cephalopods.

The biggest problem living as a squid at 5000 meters depth is the pitch black environment you have to hunt in. A great variety of cephalopods have adapted to their surroundings in the most extreme ways. One of the easiest feeding strategies is what we call “passive hunting”, and one of the more scary-looking squid known to science – the genus Magnapinna – uses this technique in the most bizarre way. Known commonly as Bigfin squid, or Long-armed squid, this group is known for its irregular big fin-size and extremely long arms. Although previously only known from caught juveniles, in 2007 an eerie video was made by a research facility in the Gulf of Mexico. What they saw was a 8 meters-long adult squid, floating around in the abyss.

Another more obvious feeding strategy is active hunting: squid are known to chase and ambush their prey using their intelligence and extremely complicated eyes. While we know that the eyes of squid are highly adapted and look similar to those of a mammal, there’s one species that takes it a step further. The so-called strawberry squid (Histioteuthis heteropsis) gets its name from the strawberry-like appearance of its skin. The light-producing speckles, or photophores, are supposed to confuse predators. What’s more interesting however, is the fact that it has one “normal” eye and one big green eye. It is believed that the smaller eye detects bioluminescence generated from potential prey, while the other eye watches the sky and filters faint light from above.

Histioteuthis heteropsis

While the strawberry squid tries to confuse its own predators, sometimes the best defense is simply being bigger than the predator. Some squid have evolved to be gigantic, take for example the Humboldt squid (Dosidicus gigas) from the gulf of Mexico. The human sized squid are known to be hostile towards divers and even hunt in packs – sometimes referred to as “a squad of squid”. An even bigger squid can be found in the deep: the Giant and Colossal squid (genus Architeuthis and Mesonychoteuthis) are known to reach sizes over 10 meters. There is only one animal capable of fighting a gigantic squid: the 16-meter long Sperm whale. Although never observed by biologists, evidence of squid-whale battles can be found on stranded whales. Circular marks, believed to be caused by the suckers of the squid, cover the hide of several found Sperm whales.

Lastly, there’s one group of cephalopods often overlooked by the general public. Having the creepiest name from the deep sea, the Vampire squid is one of the most interesting organisms on Earth. Its Latin name Vampyroteuthis infernalis literally means “vampiric squid from hell”, but its name is scarier than the animal itself. The Vampire squid feeds on the so-called deep sea snow: flakes of waste material that slowly falls to the ocean floor. It uses a long thread-like appendage to collect the snow and brings it to its mouth.

Thought to be the common ancestor of both squid and octopi, the bright red molluscs share a lot of characters with the other cephalopods. There are however some differences. When threatened, Vampire squids cannot simply swim away. Instead, they use an unique arsenal of defensive strategies. The filaments between their tentacles can be used to protect their soft bodies, exposing spiny structures on the inside of the tentacles. In addition, Vampire squid have no ink-sacs like other lineages, but can emit fluorescent fluids to scare predators away.

There’s a lot we still don’t know about the deep sea and its inhabitants, but every day new species are being discovered by marine biologists. We don’t have to look for other planets to find aliens, the weirdest organisms can be found below the waves, waiting for us.

What’s a seamount? 

Seamounts are mountains on the ocean floor that don’t reach sea level, generally formed from extinct volcanoes. Davidson Seamount at Monterey Bay National Marine Sanctuary is 7,480 feet tall — yet its summit is still 4,101 feet below the sea surface! This “oasis in the deep” is home to several unidentified deep-sea organisms, like this mollusk.
