sea turtle

May 23rd is the world sea turtle day.


About 40 of these sea turtle species are endangered.

Sea turtles are found all over the world except at the polar region. Flat backed sea turtles are exclusive to the northern Australian coast.

These are amphibious in nature and can divert to anaerobic respiration for a long period. Diet wise they can be herbivorous, carnivorous or Omnivorous, many a time they change with age.

By and large sea turtles are not very social animals though they do congregate off shore during the mating season. Sea turtles take decades to mature. When the female hatches it is in batches of 50-200 and these are hidden in the sand. But the success of hatching is very low about 0.01% as the predators are many. The sex of the hatching depends on the temperature increasing temperature decreases the hatching time resulting in greater number of female hatching's.
