Turtles
Olive Ridley Turtle
Lepidochelys olivacea · Marine reptile, family Cheloniidae
The olive ridley is the ocean's commonest sea turtle and one of its least seen by divers: a modest, round-shelled animal in gray-green that spends its life offshore rather than posing on reefs. Its fame rests on one of nature's numeric marvels: the arribadas of Ostional and Nancite in Costa Rica and Odisha in India, when a season's females arrive in coordinated waves and beaches vanish under nesting turtles. Underwater encounters are surface crossings: a small head raised mid-ocean, a pair drifting in the blue off Baja or the Revillagigedos. Sheer abundance hides real vulnerability; a species that concentrates itself so densely can be hurt at scale just as fast.
Onde e quando ver um
"Residente" significa que a maioria dos mergulhos naquele destino os encontra; "sazonal" significa presença confiável nos meses listados; qualquer outra coisa é um bônus, não um plano.

Melhor mês, em resumo
Entendendo-os
Habitat: Open tropical ocean and soft-bottom coastal shelves; not a reef turtle: most of its life passes offshore
Distribuição: Pantropical, with enormous eastern Pacific and Indian Ocean populations; mass-nesting beaches in Costa Rica, Mexico, and India
Comportamento: Famous for the arribada: synchronized mass nesting in which tens of thousands of females storm a single beach over a few nights, a strategy that swamps predators. At sea it drifts and forages alone, often logging motionless at the surface far from land.
Dieta: Crustaceans, jellyfish, tunicates, and small invertebrates taken in open water and on soft bottoms
Tamanho: normalmente cerca de 0.65 m; documentado até 0.75 m (carapace length; the smallest sea turtle alongside its Kemp's ridley sister species).
Como se comportar perto de um
Arribada beaches are strictly managed: enter only with licensed guides under national park rules. At sea, give floating turtles space; they may be resting, mating, or accompanied by boats' propellers too often already.
Conservação
Vulnerable; regulated egg harvest at Ostional coexists with strict protection elsewhere, while trawl bycatch (answered by turtle excluder devices) and coastal development press the big rookeries.
