![]() Although Kemp’s ridleys were protected in 1966 by the Mexican government, the population still plummeted to 2,000 by the 1960s and to less than 300 nesting females by 1986. In the 1960s numbers were reduced to less than 2,000 turtles.Kemp’s ridleys mainly nest on a remote beach in Mexico near the village of Rancho Nuevo (about 161 km, or 100 mi., south of the Texas border.) In 1947, scientists witnessed an arribadas of more than 42,000 Kemp’s ridley turtles in one day.Some people illegally collect turtle eggs for food and for their alleged aphrodisiac effect.Scientists estimate that more than half of the sea turtle nests on the coast of Florida were washed away by the four hurricanes hitting the coast in 20.ĭuring cold water events, when coastal water temperatures suddenly chill to below 10☌ (50☏), sea turtles may become cold-stunned-floating at the surface and unable to swim. Almost 90% of sea turtle nesting in the continental U.S. Hurricanes can severely impact sea turtle nesting success. Unfortunately, a cure for fibropapillomas does not exist. Fibropapillomas are most common in green turtle populations (especially in Hawaiian waters), although other sea turtle species are also susceptible.įibropapillomas may be at least partially caused by ocean pollutants. ![]() These growths can reduce vision, obstruct normal swimming and feeding and increase susceptibility to secondary parasitism and infection. Sea turtles may develop wart-like tumors (fibropapillomas) on their skin and internal organs. More than 90% of hatchlings are eaten by predators.įlatback turtle nests are susceptible to predation by monitor lizards, dingoes, and introduced foxes. Killer whales have been known to prey on leatherback turtles.įishes, dogs, seabirds, raccoons, ghost crabs, and other predators prey on eggs and hatchlings. Tiger sharks, in particular, are known for eating sea turtles. Since they may take 40 years to mature, a lifespan of more than 60 years is feasible.Īdult sea turtles have a few predators, mostly large sharks. Green sea turtles are the latest to mature and have an estimated reproductive life of about 19 years.Once sea turtles reach sexual maturity, they may have an estimated reproductive life of about 30 years.
