deep sea species


This ghostly deep sea creature is a newly discovered fish found in the Mariana Trench. It was found at arecord depth of 26,722 feet (8,145 meters) during an expedition led by Jeff Drazen and Patty Fryer of the University of Hawaii.

Marine biologist believe it to be a kind of snail-fish but are unsure due to its odd anatomy. It has broad, translucent fins, “stringy appendages,” and a tail that allows it to glide gently through the water. It appears to be ‘rowing’ through the water with its strange fin-like appendages. It also has a weird snout that looks like a  ”cartoon dog snout.”



Animals that make me extremely uncomfortable
  • Members of the genus Pipa (the back-brooding toads) and other pipids
  • Botflies and other dermal parasites
  • Rat kings (when the tails of many rats get inextricably tied together)

it’s not even there at first

Derek kinda just tells these two bumbling idiots to get off his property and ends up, for reasons known only to whatever higher power exists to fuck with his life, stuck with them

and it’s not there, it’s not present in the first scent that he files away under the heading ‘Stiles’ in his head, which is slightly salty and warm but lacking in substance, a little like stale popcorn

Derek doesn’t think twice about it

a person’s scent can and does change throughout their life and it usually coincides with major life events

becoming sexually mature for one

the change happens gradually. Derek’s realisation does not

it goes like this

These are Scaly-foot snail (Chrysomallon squamiferum), an iconic vent endemic gastropod known only from the Indian ocean deep-sea hydrothermal vents, at more than 2500 metres deep.

This unique snail species lives just beside black smokers that are churning out superheated water exceeding 350°C. Has also harnessed the power of chemosynthesis, housing endosymbiotic bacteria in an enlarged part of its gut. This produces the energy it needs. it has a food factory inside its body and doesn’t even need to feed! This is likely the reason it can grow to about 45mm in size, when most of its close relatives without endosymbionts are only 15mm or smaller.


Hydrothermal vents in the Southern Ocean are the physiologically most isolated chemosynthetic environments known. Recently, UK researcher has discovered the first species of yeti crab known from these environments, where is the dominant macrofauna - With 700 crabs per square meter.

Kiwa crabs, aka Yeti crabs are currently three known species, K. puravida and K hirsuta, which are from the deep sea off Costa Rica and the hydrothermal vents on the Pacific-Antartic Ridge.

The new species called Kiwa tyleri, has adapted to this very limited sized habitat, by living in highly-packed densities and by relying on bacteria they grown on they fur-like setae for nutrition.

Orange Roughy (Hoplostethus atlanticus)

Also known as the Red Roughy, Slimehead or Deep sea Perch, the orange roughy is a deep sea species of slimehead (Trachichthyidae) that inhabits the bathypelagic zone in the Western Pacific, eastern Atlantic, Indo-Pacific, and Eastern Pacific oceans. Orange roughy are sluggish and generally feed near the bottom, feeding mainly on zooplankton like crustaceans, small fish and squid. Orange roughy are noted for their extraordinary lifespan, with individuals living up to 149 years old. They are slow-growing and late to mature, which might cause their long lifespan.

jw is a yeti crab also soley terrestial like you said a coconut crab was? like is there a relation to the evolution or did gamefreak pull another remoraid/octillery on us lol

Haha, far from it, yeti crabs or yeti lobsters (same thing) are deep sea species that live around hydrothermal vents! There is a similarity though, neither coconut crabs or yeti crabs are TRUE crabs but are within a sister group to the true crabs, the Anomurans.  

The crustacean order Decapoda (meaning 10 legs) includes the most familiar crustaceans, such as crabs, lobsters, shrimps, prawns, crayfish etc.  You can further split this order into 3 infraorders: Brachyura (meaning short-tail) which includes the true crabs, Macrura (meaning long-tailed) which includes lobsters, crayfish, shrimp etc., and finally Anomura (meaning different tailed) which includes crustaceans that are sometimes described as having undergone carcinisation (the development of a crab-like body form), often through tucking  and includes a variety of groups, such as porcelain crabs, king crabs, squat lobsters (yeti crabs are squat lobsters) and hermit crabs (coconut crabs are just a big type of hermit crab) - but just to reiterate, these are not true crabs. It’s easier to imagine them as lobsters that have tucked in their tails to look like crabs.

Anyway, another Anomuran that could fit the bill of this new fluffy crab, and is a littoral (shore level) species rather than deep sea, are the hairy stone crabs (though they are not quite as ridiculously white and fluffy as the yeti crabs!)

  • Deep sea divers discover new species every time they take the plunge and you can discover yourself if you dive deep enough too
  • Sequoia trees can live for thousands of years and have watched the world change countless times and you will watch change happen too, and I hope it’s for the better
  • You will love something so much one day that it will make you blind with happiness and all the little things and even the big things that hurt won’t be able to touch you any longer
  • Copepods are hundreds of times smaller than you and they are the base for entire reefs 
  • Blind cavefish don’t have eyes and they will never be able to look at flowers or puppies, but you can and you should look at them as often as possible
  • Go on as many adventures as you are able, because one day you will become old and you will have those memories etched on your face in the form of smile marks


The deep ocean is the largest and least-explored ecosystem on Earth, and a uniquely energy-poor environment, these environments comprise approximately 66% of global sea-floor area, and hence more than half of the planet’s surface

However, these environments face every day an increasing pressure from deep-sea fishing, mining and other cumulative impacts on this vulnerable region.

Scientists from several institutions in the UK, Australia and Canada have compiled the information obtained in a thousand oceanographic expeditions to explore patterns of biodiversity in the deep ocean.

 -Amphipholis linopneusti, a brittle star from  New Caledonia by C.Harding

According to their estimates, biological models of these waters are fundamentally different from those governing the richness of species in shallow water or on land,  the article is published in Nature.

Using as model 2,099 species of brittle star or ophiuroids and other euryhaline organisms - able to adapt to a wide range of salinities. The study compared the biodiversity patterns in three different depths of the ocean: the continental shelf (20 to 200 m), the upper continental slope (200-2000 m) and offshore (2,000 to 6,500 m).

The authors found that deep-sea species have biological richness peaks at higher latitudes, compared with the continental shelf and upper continental slope. They also found that proximity to the continental margin, where the continent meets the ocean, is a significant predictor of diversity in the deep.

The findings provide a global baseline for conservation efforts across the sea floor, and demonstrate that deep-sea ecosystems show a biodiversity pattern consistent with ecological theory, despite being different from other planetary-scale habitats.

Story Summary: Just because love is capable of transcending language barriers does not mean all expressions of love can.

Author’s notes: Once upon a time, I dreamed of finishing a fic in a timely manor. 

And then one fic turned to four. 

So instead of updating anything like a good noodle I decided to contribute to the lovely Argo!AU created by the amazing @cinensis by writing this drabble. And of course because we’re both saturated with extreme levels of sap, what I had been intended to be comedic turned into two goons just being hopelessly in love with each other. As always. 

But anyway, if you aren’t familiar with the Argo!AU, I typed up the briefest explanation my tired brain could come up with on my Ao3 but I strongly recommend you check out Cinsei’s blog, not only for the beautiful art but to see this awesome AU. 

(And yes, yes I did just call him Cinsei. I’ve been calling him Cinsei. He is my Cinsei. This is a fic. A fic for my Cinsei. I’m moving to Canada and living in his closet, guys. It’s gonna be great because screw Cornfields, Illinois)

Okay anyway. As always, the fic is under a cut because length. And you can read here at Ao3!
