Sunbathing, yeah!

Spotted this little sand lizard (Lacerta agilis) on the edge of forest. It was sunbathing with pleasure between grass leaves.

Lizards, like other reptiles, are ectotherms which means they take heat from external sources. That’s why in summer it is common to find snakes, lizards and turtles in places well-exposed places that enable them to take long sunbaths, like stones.

In contrast, mammals and birds do not need to look for fancy beach spots. They (including us, humans) are endotherms. Due to efficient metabolism and insolation made of fat, hair, feathers we create our heat ourselves.

Still, we do like to take sunbaths, don’t we?
