Olive ridley sea turtles are the smallest of the sea turtles. They are widespread in tropical waters in many parts of the world. In the Pacific Ocean, they are commonly found around Mexico and Central America; however many have been known to migrate as far south as Peru.
Olive ridley sea turtles are strong divers, and have been known to dive up to 150 m in search of crabs, sea urchins and other bottom-dwelling creatures. They also roam widely in the open ocean in search of sea jellies.
Like all sea turtles, olive ridley sea turtles are threatened by habitat destruction, pollution, poaching and harvesting at their breeding beaches, disease, and mortality in fishing gear.
Although an olive ridley sea turtles has only been seen once in British Columbia, there has also been occasional sightings of olive ridley sea turtles in Oregon and Washington waters in recent years. As our oceans change, we might expect to start seeing olive ridleys on Canada’s Pacific coast.
