Rays
Southern Stingray
Hypanus americanus · Cartilaginous fish, family Dasyatidae
The southern stingray is Caribbean sand made animate: a gray-brown diamond that erupts from an apparently empty bottom, wingtips rippling, whip tail trailing, a cloud of silt hanging where it lay. Watch a flat for ten minutes and its excavation pits reveal a workaday hunter that spends its life reading the sediment for buried shellfish. At Grand Cayman's sandbar the species runs a second career greeting visitors by the dozen, velvet wings brushing snorkelers in water hip-deep, an interaction refined by rules on feeding and handling. In its wild mode it is wary, quick, and best appreciated from a body length away.

Onları anlamak
Habitat: Sand flats, lagoons, and seagrass beds; buries itself to the eyes between foraging bouts
Dağılım: Western Atlantic from the mid-US coast through the Gulf of Mexico and Caribbean to southern Brazil
Davranış: A diamond-shaped bottom forager that leaves feeding pits across every Caribbean sand flat, usually trailed by a jack or snapper hoping for leftovers. Ordinarily retiring: the famous boldness at Grand Cayman's Stingray City is learned behavior from decades of fishermen's scraps, now managed as a wildlife attraction.
Diyet: Worms, crustaceans, and small fish excavated from sand with jets of water and flapping wings
Boyut: tipik olarak yaklaşık 1.0 m; şu ana kadar belgelendi 1.5 m (disc width; large females dwarf males).
Yanında nasıl davranılır
At interaction sites follow staff handling rules and keep feeding to guides; on ordinary dives, don't hover directly over a buried ray, don't dig them out, and give feeding animals space to work.
Koruma
Near Threatened; inshore fishing and habitat loss press on it outside protected areas, while interaction-site populations are monitored for the effects of feeding and handling.
