For what kind of external environment is a saltwater fish adapted?(2 points) Responses isotonic environment isotonic environment hypotonic environment hypotonic environment hypertonic environment

Saltwater fish are adapted to a hypertonic environment. In a hypertonic environment, the concentration of salt in the surrounding water is higher than that in the fish's body. To cope with this, saltwater fish have adaptations that help them retain water and excrete excess salt.
