Also known as the Pacific ridley sea turtle, olive ridleys are the smallest and most abundant of all sea turtles found in the world. Scientific name: Lepidochelys olivacea

As the smallest of the seven species of sea turtles, they only reach a length of about 60 centimetres. They are found throughout the world’s tropical waters.

Olive ridleys are considered to be one of the most numerous sea turtle species, and are famous for congregating in huge numbers to nest.

These mass nesting events are known as ‘arribadas‘ when as many as 50,000 female turtles can gather in a single night on the same beach to lay their eggs. These ‘arribadas‘ can be be found in Costa Rica, for example.

However, in Guatemala we find that females visit beaches along the Pacific Coast throughout the year, choosing to come up to the beach in much lower numbers ranging from 1 to 200 females on any one night.
