Poison dart frogs, particularly those of the Dendrobatidae family, are not strong swimmers. While they are generally excellent climbers and can move swiftly on land, they are not adapted for swimming and are not considered aquatic creatures. These frogs are mostly terrestrial and can be found in tropical rainforests of Central and South America.
Poison dart frogs have relatively delicate skin, which can be adversely affected by prolonged exposure to water. Their skin contains toxins that they obtain from their diet in the wild, and these toxins are what make them poisonous. Therefore, they tend to avoid water and are not built for swimming like some other amphibian species.
It’s important to note that not all species of dart frogs are equally toxic, and the level of toxicity can vary depending on their diet and environmental factors. In captivity, where they are not exposed to their natural diet of certain ants and other small invertebrates, they may not be as toxic as their wild counterparts. Nevertheless, their reluctance to swim remains a characteristic of these frogs.
