Every year some classes of the French school of Pondicherry work on nature projects in English. 2009 was the year of the sea turtle. This year Mr Giroux has decided to make 4ème2 and 4ème3 discover the sleeky world of snakes! Mme Mathis will help him from a distance (because she's not too keen on meeting snakes!) We are also joined by the 6 euro who will be working with Mme François and Mme Rollinde on the disappearing common sparrow. Mr Chaitanya will work on both projects.
Olive ridleys' incubation
To incubate is to lay eggs. Sea turtles lay 50 to 100 eggs by clutch . They mostly nest in the seashore of Africa and Orissa. They lay 1 to 9 clutches per year.
The embryo's development is possible only in temperatures between 28 to 32°C. If they not suit to the climat, we should incubate them artificially.
Incubation time is 45 to 70 days. When the embryo develops, it may depend on the temperature. Higher temperature produce more females and lower temperature produce more males.
At last the new sea turtles are ready to hatch (mostly in summer).
