Reading
In a first for the US west coast, two olive ridley sea turtles were seen nesting on Orange county beaches in California. One was recorded near Seal Beach, and another on Huntington Beach. The cases were documented by officials and confirmed as two different turtles.
Olive ridleys usually nest much farther south, in Mexico and Central America. Scientists are discussing theories for the change, such as warmer coastal waters, recent hurricanes and El Niño. The eggs are expected to hatch in 45 to 60 days. Because temperature affects sex, very warm sand can produce mostly females.
The new nests have been surrounded by fences to reduce risks from predators, high tides and people. Locals are advised to keep at least 50 ft away and not interfere. To report a sighting, tell a lifeguard or call Noaa's marine animal stranding hotline. Rescued turtles can also be seen in rehabilitation tanks at an aquarium in Long Beach.
