Getting That Croaking Lizard Off The Wall

Written by Ken

Ever notice how croaking lizards can climb ceilings while perching happily for hours on the smoothest walls? Late last year, University of the West Indies (UWI) researchers reported that tiny little hairs, not chemical glue, are responsible for the reptiles being able to cling to surfaces.

A close-up of a croaking lizard toe shows that it is covered with hundreds of
thousands of hairs known as setae. The tip of each tiny hair has hundreds of even tinier pads called spatulae. Biologists had for years assumed that croaking lizards used something akin to glue. However, close examination with electron microscopes now show they have millions of tiny hairs.

The hair or setae, is only about 100 micrometers long – about the width of two human
hairs. Each setae ends with 1,000 even tinier pads at the tip. As I understand it, "One setae can lift the weight of an ant. A million setae, which could easily fit onto the area of a dime, could lift a 45-pound child and a gecko using all of its setae at the same time could support 280 pounds."

What this means dear friend, even if you wanted to, however hard you try, you can’t pull one of these croaking lizards off the wall.

Just thought that this is important enough information to share. The next thing, it is not true either that croaking lizard can’t harm…I personally would go mad trying to pull the creepy creature off the wall.
