Hot Turtle Eggs

 

It never ceases to amaze me how easily, quickly, and adequately animals can adapt to new surroundings.  I loved my ecology, vertebrate zoology, and ornithology classes in college.....SO interesting to learn about different species overcoming threats and environmental changes.  Animals are truly awesome.

ScienceDaily reports that researchers found turtles that actually evolved in their egg-laying to accommodate higher beach temperatures.

I thought that was what digging a deep hole was for....

Well, burying the eggs is mainly to keep them WARM, not to even out the temp....and also to protect them from predators.  A study was done on Ascension Island, off the coast of South America, for the Green Turtle.  Mothers would travel from the coast of S.A. to this tiny island to lay their eggs, mainly because it was where they themselves hatched (something I didn't know!).  There were two beaches in the study, and though they were only 6 kilometers apart, the temperatures varied around 3 degrees.

It doesn't seem like much, but after the eggs were put into warm incubators, it was found that the eggs from the warmer beach thrived much more than those from the cooler beach.  COOOOOOL.

These turtle mommas know what they are doing!
