Where Do Lizards Poop?

According to a research done at the university of Antwerp, lizards exhibit some similarity in their choice of ‘toilet’. In the controlled experiment, 90 lizards were each placed in an enclosure with different sizes of rocks. Surprisingly, 80% of the lizards pooped on the largest rock.

It has been previously indicated that wall lizards communicate with their fecal droppings. Male lizards mark their territories with feces so that other males can keep off. So, defecating on the biggest rock suggested an attempt to make their signals as conspicuous as possible.

Another explanation for this is that lizards spend most of their time on large rocks, to have a good view of possible predators. The research doesn’t however conclude on the possible motivation for the observed behavior. But it suggests that lizards leave their poop in conspicuous areas as a sign of communication.

Other diseases that can be transmitted from lizards to humans include Leptospirosis, botulism and Campylobacteriosis.
