Are there any salt water amphibians?

Question

I should have been a biologist, not an engineer, and then I'd know this shoite

Answer 1

Every answer so far has been wrong. I really wish people wouldn't just guess at the answers to get points.

There is a species of saltwater amphibian , but just barely. The crab eating frog of south east Asia commonly lives in mangrove estuaries. It can survive and even breed in brackish water without diffciulties.

It can and does occasionally venture into water with salt levels equivalent to the open ocean, but prolonged exposure dehydrates it and must retreat to fresher water to rehydrate every few hours.

Crocodiles and turtles aren't amphibians. They are freakin' reptiles. They've got scales for pity's sake.

Answer 2

Cool question! My initial reaction was, "You dork! Don't you know about sea turtles?" But then I realized turtles are reptiles. ( I'm a mathematician who should have been a biologist.)

Evidently, there are no marine amphibians. The reference I found claims it is because of their thin skin, but many marine animals have thin skin. So what about jellyfish?

Besides, there are toads in the deserts, so amphibians have figured out how to live in the desert with thin skin. Isn't that just as hard?

Finding that impossible to believe, because in biology there is an exception to everything. I consulted my Peterson's Field Guide (Stebbins,1966) came across a reference to a marine toad. However, "Bufo marinus", proved to be a red herring. According to Wikipedia, the tadpoles only survive salt at a concentration 15% that of seawater. However this toad has invaded Australia, where toads have previously not lived, so perhaps with time, it will invade the oceans also, befitting its name.

So the existence of a marine amphibian seems to be the exception to the exception.


AAARGH! The previous poster scooped me while I was checking this out, but his species sounds brackish, not totally marine.

How wold a person define "marine", by where the juveniles live, or do the adults' habitat count too?

Answer 3

There are no known saltwater amphibians

Answer 4

I'm sure there are, salt water crocks and turtle's maybe or are they reptiles

Answer 5

There are salt water crocodiles, that any good?.
