Sea Turtles "Tortugas"


The Knutz family got a real treat this last Sunday when we went to the coast. Our host, Enoch and his family took us to a sea turtle conservation project where local fisherman in cooperation with the University of Michoacan are working to protect sea turtle nesting grounds. The site was less than a couple acres in size. But what a joy to share in the this conservation effort. We were able to watch as one of the fishermen and Enoch's son Erwin dug up a nest of hatchling turtles.


Sea turtles begin their lives as eggs buried by their mothers on a sandy beach. After 45-70 days of incubation, baby sea turtles emerge from their sandy nests and immediately head for the ocean. They reach maturity in 25 to 50 years. After mating, adult females often cross ocean basins back to their original nesting beaches to lay eggs and renew the cycle. They are excellent navigators, able to sense minute variations in the Earth’s magnetic field. The chances of surviving to adulthood are extremely low, so turtles lay up to 150 eggs per nest and may nest up to three times in a season. They nest every two to three years.

The Black Sea Turtles that we released have declined globally 80 percent over the last 150 years. Breeding populations of black turtles off Mexico are listed as endangered under the Endangered Species Act. In the 1980s, black turtles at their major nesting beach, Colola Beach in Michoacán, Mexico, declined significantly from 5,500 nesting females to a low of 171. The population is now increasing, though numbers are still well below their natural levels.
There are two other varieties of sea turtles that nest at this site, one of them being the leatherback sea turtle. Since 1980, leatherbacks have declined by 95% at their major Pacific nesting beaches. If current trends continue, Pacific leatherbacks will go extinct within the next few decades and there is a 50% chance they will be gone within 11-12 years.



This was our eniter party. Enoch and Easter have three sons who are gentlemen with a heart to serve others. Enoch and his family have really befriended us and have invited us to several outings. Enoch teaches welding and physical science. He always has smile on his face and a good attitude.


The two girls are Karen (in the red shirt) has been a wonderful translator for us. She has also become good friend to Molly. Her sister Adeline is a joy to be with as well. They live in L.A. but are spending this year in La Huacana with their aunt who is also in our group photo (left).
