Explanation:

Olive ridleys are found only in warmer waters, including the southern Atlantic, Pacific and Indian Oceans..
Olive ridleys are among smallest of the sea turtles, weighing up to 100 pounds (45 kilograms) and reaching only about 2 feet (65 centimeters) in shell length.
These turtles are solitary, preferring the open ocean. They migrate hundreds or even thousands of miles every year, and come together as a group only once a year for the arribada, when females return to the beaches where they hatched and lumber onshore, sometimes in the thousands, to nest. Olive ridleys have nesting sites all over the world, on tropical and subtropical beaches.
During nesting, they use the wind and the tide to help them reach the beach. Females lay about a hundred eggs, but may nest up to three times a year.The olive ridley is mostly carnivorous, feeding on such creatures as jellyfish, snails, crabs, and shrimp.
 They will occasionally eat algae and seaweed as well.
Though the olive ridley is widely considered the most abundant of the marine turtles, by all estimates, it is in trouble. Rough estimates put the worldwide population of nesting females at about 800,000, but its numbers, particularly in the western Atlantic, have declined precipitously.
 Fishing nets also take a large toll, frequently snagging and drowning these turtles.
 Odisha coast is considered the only place apart from Costa Rica to witness mass nesting by Olive Ridleys. Between five lakh and 10 lakh turtles come to the state every year for mass nesting.
The Convention on Migratory Species and the Inter-American Convention for the Protection and Conservation of Sea Turtles have also provided olive ridleys with protection, leading to increased conservation and management for this marine turtle.
  All the species of sea turtles in the coastal water of Orissa are listed as "vulnerable" in the IUCN Red Data Book.
