Not all turtles live on land. These two spend almost their entire lives in the water, but they could not be more different. The African sideneck turtle lives in lagoons and swamps of West and Central Africa. It belongs to the so-called side-necked turtles: instead of pulling its head in, it folds it to one side. It can close the front of its shell like a door, and when the dry season arrives it buries itself in the mud until the rains return. The common snapping turtle is from North America and has a well-earned reputation: its jaws are very powerful. Since it does not fit entirely inside its shell, it defends itself by biting. In the water, however, it is usually calm and prefers to hide. And an important message: in Spain, the snapping turtle is an invasive species. Never release a turtle or any exotic pet into the wild.
