Question

how do marine animals adapt to hypertonic sea water????
​

Answer 1

The turtle, which evolved to close over its ribs

and backbone with hard material, making them

both into very hard continuous protective layers,

even though underneath it all they have a

skeleton similar to our own.

Electric eels, which evolved the ability to store

their bodies innate electrical energy until such

time as they needed to deliver it as a shock,

either as a protection or as a method of stunning

their prey. This one is a great example of an

adaptive evolution that has more than one

use, and a big poke in the eye to creationists

who deny evolution, as they like to argue that

evolution is supposed to be about things always

having a specific purpose, which is unlikely, so

God did it instead. Whereas in fact evolution

is somewhat random, and many adaptations

(mutations, really) are either useless or are later

found to have a use

Answer 2

Answer:

Explanation:

Cells regulate their osmolarity by pumping ions across their cell membranes or opening and closing ion channels. Large multicellular organisms have organs that excrete extra salt. If you are referring to animals that evolved from terrestrial animals, they usually excrete salt from either a specialized salt gland (birds and reptiles) or their kidneys. (Mammals). The salt content of sea mammals is similar to that of terrestrial mammals. I don't know about that of seabirds or marine reptiles but I assume it's similar to their land relatives.
