Mantis Shrimp: The mantis shrimp can come in countless varieties, over 400 species. These aggressive and typically solitary sea creatures spend most of their time hiding in rock formations or burrowing intricate passageways in the sea bed. They can either spear or smash their prey, each method being rapid and deadly.
Hooded Seal: These seals are found in the central and western North Atlantic. They’re named hooded seals because of the species’ unusual sexual ornament, a peculiar inflatable bladder on the head of the adult male. To attract a mate, the seals inflate the bladder.
Dumbo Octopus: These octopi are of the genus Grimpoteuthis, and have ear-like fins that come out of their heads. They hover above the sea floor, searching for polychaetes, pelagic copepods, isopods, amphipods, and other crustaceans for food (which they swallow whole).
