*Crazy to imagine there was such thing as salt water amphibians.*

[@melvinshine9841]

I think modern amphibians can't handle salt water because it has an adverse effect on their skin. I can't remember how it works.

[@MisterSiza78]

@@melvinshine9841 maybe because it will dry out due to osmosis?

[@tec-jones5445]

@@melvinshine9841 their skin is very delicate, as they need it to absorb water through their skin. Unlike these ancient ones, today's amphibians not only need water to breed, but also to stay alive as adults. They don't have scales or tough skin to keep water in. So they are restricted to water. Because of this permeable skin, salt can easily damage because of how easily it is absorbed through water. And without proper salt filtering kidneys or organs, the salt becomes toxic. That's not to say salt water amphibians might not appear again. If the right selective pressures are made available, then such amphibians might just evolve independently again given enough time.

[@timeshark8727]

You are correct sir! The higher salinity of ocean water will pull water out of modern amphibians (and most freshwater fish) too quickly for them to replenish it. Mainly due to how poorly their skin tends to hold in water to begin with.

[@timeshark8727]

doesn't surprise me, frogs tend to try eating anything that can fit in their mouths.

[@TctyaDDKhang]

Idea: Learn to use an egg "I was already doing that" Use a stronger egg. Put water in it. Have the baby, on land, in the egg, water is in the egg, baby in the egg, in the water, in the egg. Works for me. _bye bye ocean_

We have some. Some of the earliest "spiders" come from the carboniferous period, mygalomorph spiders, which include modern day tarantulas, come from this period and we know of some true spiders from the end of the Jurassic period and the Cretaceous period. It's likely they evolved from sea-whip scorpions that lived along side other arachnid ancestors like Brontoscorpio.

The egg technology was the key....of course primates give live birth, as do some present-day reptiles and some fish. The evolutionary “plan” astonishes me.
