Brown catshark : ウィキペディア英語版 | Brown catshark
The brown catshark (''Apristurus brunneus'') is commonly found in the Pacific Ocean, ranging from the northern Pacific waters off the coast of British Columbia and south to the Baja California peninsula in Mexico. They may live as far south as Ecuador and Peru. Brown catsharks are deep-water sharks that live on the outer continental shelf and the upper slope. They have been known to live at depths ranging from 30 to 650 m and live on the bottom, usually in muddy or sandy areas. The brown catshark, when originally described, was called ''Catulus brunneus''. ==Description== Brown catsharks have long, slender bodies with broad, bell-shaped snouts. They are dark brown with light-colored markings on the posterior margins of their fins. Their bodies are soft and flabby, with a weak skin that can easily be harmed. Brown catsharks' two dorsal fins are the same size and do not have spines. The first dorsal fin originates to the front of the pelvic fin and the second dorsal fin is located in front of the anal fin's insertion. They typically reach a maximum size of 68 cm in total length, but they average between 30 and 60 cm.
