major huge...the one last night measured 142 cm from top to bottom of carapace...tail and head not included.
Survival rate: without the present people intervention 1 out of a 1,000 survives. That used to be enough to keep the population going. Now it is not enough. They are critically endangered.
Here are some stats. I think leatherbacktrust.org has some, too.
In the 1980s: 200 leatherbacks a night would come ashore to nest
2010: 106 nests for the whole season!!!!!!!!!!!!!!! There are 29 ladies who are the layers. They usually come every 3 or 4 years. In that season that they come, they return 8-9-10 times throughout the season and lay from 50-90 eggs. Or something like that. The hatching rate is 57% for the leatherbacks.
