Frogs are a group of amphibians that can be placed in various subcategories in relation to their built, habitat or evolutionary path.
Although in captivity we tend to simplify this by placing most of them either in the poison dart frog category or the treefrog category.
Most frogs have a permeable skin, that is always slightly moist. Many frogs have quite smooth skin, but many exceptions apply.
Another very clear difference between the two categories can also be seen at the feet. Treefrogs have more distinct toes with suction cups.
More frogs prefer a humid climate, but not all like water and can even drown, so this must be taken into consideration when creating their housing.
Many amphibians lay their eggs in or near water and the young, that are called tadpoles need these circumstances to grow, after a few weeks they develop legs and start leaving the water.
Poison dart frogs
The poison dart frogs are very vividly coloured to display their toxicity. Treefrogs have less coloration but are able to change their colour during the day.
