Hatchlings range from 42-48 mm in straight He landed and filmed the turtles as they nested. Despite incubating together, the eggs from one nest do not usually produce hatchlings that are all the same gender. The females arrive in large groups of hundreds or thousands in nesting aggregations called arribadas, which is a Spanish word for "arrivals".[19][20]. The Kemp's ridley is the smallest sea turtle. The Tennessee Aquarium offered overnight shelter and care and the turtles were eventually released to the sea.[30]. The name of this sea turtle is in honor of Richard M.
