advantages to livinig in salt water
~provides buoyancy and floats in nutrients while carrying away wastes
~fairly constant temperature
freshwater organisms
~require mechanisms to balance salt concentrations inside to outside, so requires specialized structures
difficulties of terrestrial environment
dehydration and greater specialization development
