How many olive ridley sea turtles are left

It is very hard to say how many sea turtles are left. Sea turtles are not easy to count, so we use different methods to estimate population sizes. One such measure used is the annual number of nesting events in each population. Since turtles can lay more than one clutch per year, the number of nests does not directly translate to adult females in a population.

There are also many important nesting and feeding grounds on the east Pacific coast from as far north as Canada to as far south as southern Peru. Nesting occurs at low frequency throughout much of its range, with the highest concentrations of the olive ridley found on the coast of Orissa state, India.

The principal beaches are Garhimatha, Ruchikulya and Devi River mouths. Populations in northern Australia and south-east Asia are known to be different genetic stock to the Orissa turtles. Populations of olive ridleys are reported to have declined in Pakistan, Myanmar, Malaysia and Thailand, and possibly on the east coast of India, south of Orissa and in the Andaman and Nicobar islands.

Olive Ridley turtle. What are the main threats? The main threats which affect marine turtles are: Habitat loss and degradation Wildlife trade Collection of eggs and meat for consumption Incidental capture bycatch Climate change Pollution The belief that turtle eggs have aphrodisiac properties is a major threat to olive ridley populations in Central and South America. The illegal nature of the turtle egg trade makes it difficult to estimate the impact on olive ridley populations but seizures of eggs are not uncommon.

The largest on record occurred in October in Mexico City, when a lorry was seized containing over , olive ridley eggs, taken from a single beach. The size of this haul indicates a large demand for eggs in Central America and the Hispanic communities of California and Florida. Olive ridleys were once killed in large numbers for meat and leather.

There were many economically important slaughterhouses on Mexico's Pacific coast, where officially over 1 million turtles were killed each year during the s. This slaughter was reduced when legal quotas were introduced, although a smaller illegal industry persists. Male olive ridleys can be distinguished from females by their tails, which stick out beyond their carapace. A groundbreaking bipartisan bill aims to address the looming wildlife crisis before it's too late, while creating sorely needed jobs.

Olive Ridley Sea Turtle. Classification: Reptile. Description Olive ridleys are considered the most abundant sea turtle in the world. Diet The olive ridley is omnivorous, meaning it feeds on both plants and animals, including algae, lobster, crabs, tunicates, mollusks, shrimp, and fish.

Behavior Unfortunately not much is known about the behavior of this turtle. Federal Endangered Species Act. International — Listed as Vulnerable facing a high risk of extinction in the wild in the near future by the International Union for Conservation of Nature and Natural Resources. Threats to Survival: Direct harvest of adults and eggs, incidental capture in commercial fisheries and loss of nesting habitat are the main threats to this species.
