Similar Assertions

Marine molluscs, like clams and snails, rely on a substance called taurine to help their cells stay the right size when the saltiness of the water around them changes — kind of like how a sponge adjusts to wet or dry conditions without falling apart.

In flounder fish hearts, taurine and potassium might help heart cells stay the right size when the salt levels in their blood change, which could keep the heart working properly in tough conditions.
