The '''longnose spurdog''' |
The '''longnose spurdog''' ('''''Squalus blainville''''') is a [[dogfish shark]] of the [[genus]] ''[[Squalus]]'', found over [[continental shelf|continental shelves]] in all oceans, at depths of between 15 and 800 metres. They reach one metre in length. |
||
The longnose spurdog has two [[dorsal fin]]s each of which has one [[anterior]] spine, but no [[anal fin]]. The eyes are distinctively large and green. The body is uniformly grey above. Males are identified by their [[valva|claspers]] (modified [[pelvic fin]]s used as [[intromittent organ]]s), while females have none. |
|||
They feed on bony fishes, like [[porgy|porgies]], [[mackerel]] and [[percichthyid]]s, as well as [[crab]]s, [[lobster]]s, and [[octopi]]. Their reproduction is [[Ovoviviparity|ovoviviparous]], with three to four young per litter. |
|||
The longnose spurdog is a foodfish, being utilized fresh, dried and salted, and smoked for human consumption. |
