Rossia glaucopis, commonly known as the Blue-eyed Squid, is a fascinating cephalopod species that thrives in the depths of the ocean. It belongs to the family Sepiolidae, a group of small, often colorful squids, and is a representative of the order Sepiida, which includes the cuttlefish.
Description & Characteristics
Rossia glaucopis is a relatively small squid, typically reaching a maximum size of around 10 cm in mantle length. The most striking feature of this species is its distinctive blue eyes, which are large and prominent. This unique characteristic gives the squid its common name. The body of Rossia glaucopis is generally cylindrical in shape, with a rounded mantle and a pair of fins that extend along its sides.
Habitat and Occurrence
Rossia glaucopis is primarily a benthic species, meaning it lives on or near the seafloor. This squid is typically found in the neritic zone, the coastal region of the ocean extending from the shoreline to the edge of the continental shelf. Rossia glaucopis prefers soft sediment habitats, such as mud or sand bottoms, often dwelling in depths ranging from 10 to 500 meters. Its distribution is geographically widespread, with populations found in the eastern Atlantic Ocean, the Mediterranean Sea, and the northeastern Atlantic.
Taxonomy
Rossia glaucopis is classified within the Class Cephalopoda, which encompasses all squid, octopus, cuttlefish, and nautilus species. Within this class, it is further categorized as a member of the Order Sepiida, a group known for their internal shells or cuttlebones. Finally, Rossia glaucopis belongs to the Family Sepiolidae, a diverse family of small, often colorful squids characterized by their short, rounded bodies and well-developed fins.
Feeding
Rossia glaucopis is a carnivorous species, primarily feeding on small crustaceans, worms, and other benthic organisms. This squid uses its powerful beak and sharp teeth to capture and consume its prey. As a nocturnal predator, Rossia glaucopis is active at night, hunting in the depths of its preferred habitat.
