Hello! My name is Ms. Elebash . Please join me as I travel to Costa Rica to study sea turtles!

I'm heading down to the land of amazing Chelonioideans...

Chelonioideans? I think that's what they could be called...Chelonioidea is the Latin superfamily name for the two groups of sea turtles which grace our oceans.

Turtles popped up during the Triassic or Jurassic period, somewhere in the neighborhood of 220 million years ago. They lived on land and were thought to be carnivores. When food on land was hard to come by, they adapted and went into the water. Here, through eons and eons of years, their appendages became flippers and their shell elongated and became more water dynamic. Their diets changed as the availability of food changed. They probably became larger as a means for self defense. Female turtles continued to lay their eggs on land. At any rate,they are old on the evolutionary stage. Scientists are studying their past to create the full story.

And scientists are also studying the present because the sea turtle population has declined 90% in the last thirty years. The leatherback in particular is listed as critically endangered. Costa Rica
has the last group of Pacific beaches where the turtles are nesting. The nightly nesting has declined from around 200 a night in the 1980s to about as little as 10 a night in 1996. I am going down to these beaches to help save the leatherback. I will be working at the Goldring Marine Biology Field Station in conjunction with Earthwatch.

Amazing? Just check out the picture.

  1. I had no idea that leatherbacks were so enormous! Or that their evolutionary path took them from land to sea! Thank you for blogging about your trip; I can't wait to hear more!
