Helicocranchia

Helicocranchia is a genus of small glass squids from the family Cranchiidae, known as piglet squid. They are characterized by possessing a very large funnel and in having a pair of small paddle-like fins which are attached to a part of the gladius which sits above the muscular mantle. These squid undergo a slow descent starting near the surface as paralarvae moving down to lower mesopelagic depths as near-adults.[2]

Species

There are three species of Helicocranchia:[1]

gollark: well, that seems like a weird view if you apply it to physical objects, which constantly change slightly when they interact with their environment.
gollark: Which poses an interesting philosophical question: if you replace all the parts of a bot one by one, is it the same bot afterward?
gollark: Yes, but newer and shinier and also different in basically every way apparently.
gollark: ????
gollark: > I hope pythonYes, Python.
