Lizards lounge for survival purposes

While your clients may be trying to catch all the rays they can this summer, don't let them forget about their aquarium-bound pets. Reptiles need their time to shine too, a recent study says. The research suggests that the idea that reptiles only sun to regulate their temperature is outdated. When they bask in the glow it's more about survival.

The study, led by behavioral ecologist Kristopher Karsten of Texas Christian University in Forth Worth, analyzed two groups of panther chameleons in order to find a connection between reptiles' diets and sunning habits. With a control group of lizards eating regular crickets and another eating crickets dusted with vitamin D, researchers discovered that lizards eating diets higher in vitamin D spent less time in the sun. As reported in the May/June 2009 issue of  Physiological and Biochemical Zoology, researchers concluded reptiles sun bathe to receive the essential vitamin.
