Frogs come in all sorts of sizes, and all sorts of colours. Some of them look like the places they live. This frog at the top is the same colour as the tree trunk it is sitting on. It is camouflaged so that it can't be seen by its enemies, and eaten.

The other frog is a very bright colour. Sometimes they look like this as a warning that they might be poisonous to eat, so it will stop other animals eating it.
