june 11th - Olive ridley day

The second smallest after the Kemp’s ridley, the olive ridley turtles weigh between 75-100 pounds (34 - 45 kg) and reach 2-2 ½ feet (roughly .6 m) in length. They are named for their pale green carapace, or shell and are the most abundant of sea turtle species.  Like the Kemp’s ridley, nest in masses referred to as arribadas. During arribadas, thousands of females may nest over the course of a few days to a few weeks. Adults reach sexual maturity around the age of 15 years.


Olive ridleys occur globally and are found mainly in tropical regions of the Pacific, Indian, and Southern Atlantic Oceans. They are primarily pelagic, spending much of their life in the open ocean, but may also inhabit continental shelf areas and venture into bays and estuaries. Arribadas occur in Mexico, Nicaragua, Costa Rica, Panama, Australia, parts of Africa, and a few beaches along the coast of India. The largest ones occur in Costa Rica, Mexico, and India. Other solitary nesting areas include Guatemala, Brazil, Myanmar, Malaysia, and Pakistan. Worldwide, they nest in approximately 40 countries.


Threats to olive ridleys include the direct harvest of turtles and eggs for human consumption, entanglement of turtles in commercial fishing gear, and coastal development.

The single highest number of Olive Ridley Turtle nesting occurs in the eastern state of Odisha in India. Every year, anywhere between 400,000 to 1,100,000 turtles come ashore in a mass nesting event called arribada! Humane Society International/India, along with its on-ground partners Action for Protection of Wild Animals, works to bring several other community based organisations and individuals under one broad umbrella to streamline conservation efforts all along the major nesting sites. http://video.humanesociety.org/assets/links/preview.php?bctid=5785775869001

Olive ridley turtles are the most numerous of sea turtles. They’re known for their mass nesting events called “arribadas” where tens or hundreds of thousands of females nest over a few days. They also have beaches where they nest individually. Learn more about these amazing turtles here: https://www.seaturtleweek.com/olive-ridley-day #SeaTurtleWeek
