The poison dart frog is like this!

When in captivity, they actually aren’t poisonous because their diet is different.

Lol what is this article?

First

Poison dart frogs are not poisonous in captivity because they do not have access to the specific insects that they would eat in the wild which contain the toxins that make them poisonous.

Also

It is a common misconception that dart frogs lose their poison in captivity. In reality, they only lose their toxicity when they are exposed to certain chemicals found in captivity, such as cleaners and pesticides

Later

They acquire these toxins as they eat certain insects in their environment that contain them. So if a poison dart frog is ever relocated to an area where these insects don’t exist, it will lose its toxicity over time.

Finally… it’s fine if you’re not worries about getting poisoned

Some people handle their poison dart frogs with gloves, but this isn’t necessary unless you have an open wound on your hand or you’re particularly worried about getting poisoned.
