Rossia is a genus of 10 species of benthic bobtail squid in the family Sepioidae found in all oceans.
[1] Each squid under genus Rossia have broadly separated fins with free anterior and posterior lobes.
[8] For species that have been studied, Rossia's diet consists of shrimps and prawns, but they have sharp and hardened beak which allows them to consume small crabs, along with fish and other cephalopods.
[9] Spawning takes place year round, where small egg masses are found on seaweed or smooth objects on the ocean floor.
[11] When the egg masses of Rossia are ready to hatch, they push the tip of the mantle against the casing to break it, followed by the rest of its body.
