The Kemp’s Ridley is the smallest of the sea turtles and has an extremely restricted range, nesting only along the Caribbean shores of northern Mexico and in Texas, U.S.A. Fifty years ago, the Kemp’s Ridley was near extinction. Although this species now shows signs of recovery, fishing nets and coastal development continue to threaten the species, and much work remains to be done before it can be considered safe.
Most restricted geographic range of all sea turtle species. Only nesting areas are in Rancho Nuevo, Tamaulipas, Mexico, and in Texas, U.S.
Non-nesting range extends between the Northwest Atlantic Ocean, the Gulf of Mexico, and the Caribbean.
Global Biogeography of the Kemp’s Ridley (SWOT Report, vol. V, 2010)
Length 60-70 cm
Mass up to 60 kg
Length approximately 25 mm
Mass 15 to 20 g
For all life stages, mostly benthic invertebrates (crabs, other crustaceans, and mollusks) and some jellies
Reproduce every 1-3 years
Lay 1-3 clutches of eggs per season
Lay 90-130 eggs per clutch
Ping-pong ball size eggs weigh approximately 30 grams each
Incubation period is approximately 60 days long
Takes 10-15 years to reach sexual maturity
Along with olive ridleys, Kemp’s ridleys are the only sea turtles species to exhibit synchronous mass nesting, termed arribadas.
During the arribadas, the Spanish word for ‘arrivals,’ tens of thousands of female turtles nest during the same 3-7 day period once a month.
Along with olive ridleys, and, to a lesser extent, flatbacks, Kemp’s ridleys are the only sea turtle species to commonly nest during the day
An incredible bi-national effort has been made to save Kemp’s ridleys from extinction by translocating eggs from beaches in Mexico to beaches in Texas, and by ‘head-starting’ juvenile Kemp’s ridleys, whereby hatchling turtles are grown in captivity to larger sizes before being released in an attempt to mitigate predation effects.
