If a marine animal has body fluids that have a lower salt content than the surrounding seawater, water will pass through the animal's body tissues from the to the because of

inside, outside and Osmosis

Explanation:

The marine animal has an hypotonic solution inside since the salt concentration is different from the environment which is hypertonic solution ( high salt content). This build osmotic potential between the inside of the organism and the environment leading to water leaving the inside of the marine organism to outside which is the environment through osmosis ( is the process where by water molecules moves across selectively permeable membrane because of osmotic potential)
