Sea Turtle Nesting


January 16, 2013

Baby rescued from a nest
From May through October, Florida beaches are home to sea turtle nests. Females come ashore during the night and lay about 100 rubbery eggs the size of ping-pong balls. They haul themselves up on the beach, dig a hole about 18 inches deep, lay their eggs and then cover them up. In about three hours they are heading back to the water. I love walking on the beach in the morning and looking for fresh turtle tracks coming from the water and then going back out again.

Here on the gulf coast the most common sea turtle is the Loggerhead. We have a very active ‘turtle patrol’ group that stakes the nests so they aren’t disturbed. In about 60 days the hatchlings make their way to the water at night and swim out to the seagrass beds where they live for several years. These little babes weigh less than an ounce and are only two inches long. Their sex is determined during incubation by the nest temperature: boys like it cool and girls like it hot.

Digging up the nest

A few days after they leave, the patrol digs up the nest and counts the eggshells. Bob and I attended an excavation this summer and were delighted to find that about ten little turtles were stuck in the nest. This gave us a rare chance to see them! They were all released a few hours later under the cover of darkness.

This past summer there were 370 nests on Anna Maria Island alone. From those nests, approximately 23,178 little hatchlings headed into the gulf. Scientists estimate that only 1 in 1,000-10,000 hatchlings live to adulthood so it’s a pretty tough life. Adult turtles can grow over 3 feet long and weigh 200–300 pounds. Sea turtles live their entire lives in the ocean and only the females come ashore to nest.

All sea turtles are endangered but I’m thrilled to see that so many are nesting in my own backyard. Perhaps next year I can join the turtle patrol. Wouldn’t that be fun?
