Turtles that eat bone, rocks and soil, and turtles that mine

Why are these turtles eating, and gnawing at, bone? Turtles seem to have high calcium requirements, with some studies indicating that they require unusually high quantities in order for shell and skeletal development to occur normally (Fledelius et al. 2005). In part, this is probably due to the extensive amount of extra bone they grow for their shells, but females also need extra amounts of calcium when forming eggs and growing eggshells: data from female musk turtles at least shows that skeletal bone density drops markedly during the time that eggshells are being formed (Edgren 1960).…MORE


About Indian Rocks Bridge

We have a HUGE responsibility to protect our children and their futures. Our Gulf of Mexico has nearly been destroyed by the Deep-water Horizon catastrophe and many families here will never recover. Paradise lost, so it goes. I’m doing my best to apolitically educate anyone that cares about the impact on our environment by technology and “for-profit” progress. We forget, too frequently that we SHARE this planet with millions of other life-forms and as the most “powerful” species, we must be more cognizant of our greed versus the well-being of our planet. Thanks again for visiting and please check back often. -Gregg indianrocksbridge@yahoo.com
