“This adorable creature is the Banded Piglet Squid (Helicocranchia pfefferi). They’re found at depths of 100m or more, and that odd appearance of a smile is caused by skin pigmentation “
Marrus orthocanna is a species of siphonophore, a colonial animal composed of a complex arrangement of zooids, some of which are polyps and some medusae. It lives at depths ranging between 200 and 800 m (660 and 2,600 ft), in the Arctic and other cold, deep waters.
