Frogs are primarily freshwater amphibians and are not equipped to live in salt water. Most species of frogs thrive in environments such as ponds, streams, and lakes that have low levels of salinity. When exposed to salt water, frogs can suffer from dehydration because their bodies are adapted to absorb water rather than deal with excess salt.
The amphibious skin of frogs is permeable, which allows them to absorb water; however, this permeability also makes them vulnerable to the osmotic effects of salt. If a frog enters salt water, its body might lose water more rapidly, leading to dehydration and potentially fatal outcomes.
While there are some amphibians that have adapted to brackish environments, frogs are generally not among them. It’s essential for frogs to live in habitats that match their physiological needs to survive and thrive.
