Nurse Shark
Ginglymostoma cirratum · Cartilaginous fish — family Ginglymostomatidae
The nurse shark is the Caribbean's resident couch dweller: a heavy-bodied, small-eyed animal the color of wet sand, folded under a ledge with its barbels drooping and its tail poking into the current. It can pump water over its gills while motionless, so entire dives pass while it does precisely nothing — then a night dive reveals the other nurse shark, nosing urgently through coral and inhaling octopus with an audible thump. At Belize's Shark Ray Alley and Bahamian feed sites they swarm like eager dogs. Its mellow reputation is deserved, right up until someone grabs one.

最佳月份一览
深入了解
栖息地: Reefs, ledges, mangrove channels, and seagrass flats; rests by day under overhangs, often in piles
分布范围: Tropical western Atlantic from Florida and the Bahamas to Brazil, plus the eastern Pacific coast of the Americas; the similar tawny nurse shark replaces it in the Indo-Pacific
习性: A sedentary, nocturnal bottom-dweller with barbels like a catfish and a tail that trails behind it lazily. Days are spent wedged beneath ledges, frequently stacked on other nurse sharks; nights are spent slurping prey out of holes. Habituated animals at feed sites become boldly food-focused.
食性: Crustaceans, mollusks, and small fish vacuumed off the bottom with a powerful suction feed you can sometimes hear
体型: 通常约 2.3 m; 记录深度可达 3.1 m (total length).
与它相处时的行为守则
No tail-pulling, no riding, no lifting resting animals for photos — behavior once common and now rightly banned. Give resting sharks their ledge and keep bait well managed at feed sites.
保育
Moved to Vulnerable in 2020 as inshore fishing and habitat loss eroded populations outside protected areas; still locally abundant in Florida, the Bahamas, and Belize.
