Frogs are the very few remaining members of the amphibia family. Other members of the amphibia family are toads, newts and salamanders. Whats make these unique is that they can move, feed and breathe on land and water. Frogs have been inhabiting earth for millions of years. We often dont come across frogs that much unless you’re in the right areas that they inhabit. However, when you do come across them its good to know if they are poisonous or not, so let’s find out how you can tell if a frog is poisonous? One day it may save your life. 

Out of the several thousand species of frogs, only a selection of them is considered poisonous. You can tell a poisonous frog by a non-poisonous frog is by its colours. Bright blue, yellow and orange are the classic colours of a poisonous frog. These bright colours are warning signs to indicate that the frog is toxic and to keep well away. 

We now understand that frogs that are brightly coloured are often poisonous. If you walk in the wild and come across any brightly coloured frogs, you must keep well away. If you are thinking of getting a pet frog, you must never adopt a brightly coloured frog. Loud coloured frogs are not safe to handle and will make you very sick and can even be a risk to your life. 

How many different frog species are there?

There are over 4700 different types of frogs in the world from the standard back garden frogs to the highly poisonous brightly coloured frogs. 

How many of them are poisonous?

Out of all the frogs globally, roughly 100 are considered poisonous to animals and humans. Contact with these frogs species can result in toxic symptoms and can be fatal to animals and humans. 

How do frogs poison you?

Frogs dont bite and they have no such venom gland to administer it. A frog will omit a poisonous toxin from their skin. When handled or often tried to be eaten, killed by other animals, they will release their secretions poison on the perpetrator’s skin.

How are frogs poisonous?

Frogs are poisonous due to the diet that they eat. Frogs eat ants and other small insects loaded with toxins alkaloids. Ants get them from the diet they eat but can suppress the toxins themselves. These toxins are incredibly toxic, but frogs can eat them with no effect on their health. The frogs then extract and store these toxins in special sacs under the skin and use them for protection. 

Can you reverse a poisonous frog through diet?

Domestic frogs will generally eat different foods. Since some wild frogs eat toxic insects, you could reverse the poisonous frogs through changing their diet; however, how long this can take is unknown, since they store the poison within their bodies and expel it when threatened. You wouldn’t know how much they have and if they have much left. 

Where can you find a poisonous frog?

The majority of poison frogs are found in humid, tropical environments in the central and south America region. Tropical rainforests harbour many of the poisonous frogs.
