Sea Turtles…………Fascinating and Endangered…………….by Pam Todd

One of the creatures that has been on the earth for an extremely long number of years is the turtle.  They fascinate me.  At one point during my teaching career, our elementary school staff decided to name our classrooms with an animal name.  There were the Pandas, Mustangs, Rabbits, Whales, Hawks, Owls, Eagles, and Bears, to name a few.  And, then there was my classroom….the Turtles.  We studied sea turtles, land turtles, wrote a class newspaper entitled “The Turtle Times,” and created turtle art, music, and poetry.  We even had a classroom turtle in an aquarium tank during one school year.  Little did we know how much he did not like that environment until I took him home for the summer, set the tank on the front porch, and by morning, he had managed to climb out and make his way into the woods, where we saw him and all hope he lived happily every after!

Green-Sea-Turtle Commercial fishing is one of the dangers to sea turtles.  Since  1983, federal law has required devices to assure that turtles can escape fishing nets be used on  all trawlers operating in U.S. waters with populations of sea turtles.  This device, called a Turtle Excluder Device, was developed by the U.S. National Marine Fisheries Service.  Shrimp can pass through it to the back of the net, and turtles can move through the trapdoor and back into the sea before becoming entangled in the net.

A second risk to the sea turtle population is polluted waters, such as those created by the Gulf Oil Spill.  Proactive creation of wildlife refuges is an attempt to provide safe, clean environments in which sea turtles can live and breed.  In 1991, 900 acres between Melbourne Beach and Wabasso Beach, Florida were acquired, with local agencies and private groups sharing the cost.  This area is an extremely important nesting place for Western Hemisphere loggerheads, U.S. green sea turtles, and the northernmost Atlantic Coast point for leatherback nesting.  This area has resulted in an increase in the number of counted loggerhead nests from ten in 1996 to 39 in 2001.  Because this refuge area is considered prime commercial real estate development, government funding is essential to preserve it.


Accidents also claim the lives of sea turtles.  They come in from the ocean to lay their eggs on beaches.   After laying their eggs, the adult females return to the ocean.  When their eggs hatch, the hatchlings instinctively crawl towards the brightest light, which should be the sky above the sea.  However, beach lighting and car lights from nearby roads often confuse them, they crawl the wrong way, and sometimes are crushed under the wheels of passing automobiles, become dehydrated, or are eaten by predators. A low pressure sodium vapor light can be used on the beaches, and this kind of lighting may reduce the disorientation of the hatchlings.  This has been encouraged in many beach communities.

Wow! I didn't know about the hatchlings following the light. I think the more we understand animals the more we can change our lifestyles to help preserve them. The changes we make may not even really matter to us (like the sodium vapor light - look at how many street lights we have up!).

I wonder how many fishermen actually follow the rules. Just my curiosity. :)

I completely agree that the more we learn about animals the better we are able to help them out. Especially in these times when animals are becoming more and more displaced in our world.

Thanks so much for sharing Pam! Turtles are one of my favorite animals!
