أشلاق (القروش و الشفانين) (sharks and rays) > Squaliformes (Sleeper and dogfish sharks) > Somniosidae (Sleeper sharks)
Etymology: Somniosus:Latin for sleepy, reflecting Lesueur’s surmise that these sharks are slow or sluggish because of their relatively small fins (hence the name sleeper sharks). (See ETYFish); microcephalus:micro-, from mikros (Gr.), small; cephalus, from kephale (Gr.), head, allusion not explained, perhaps referring to its short, rounded snout compared with other sharks then included in the catch-all genus Squalus. (See ETYFish). More on authors: Bloch & Schneider.
Environment: milieu / climate zone / depth range / distribution range
