Despite its name, the Pacific sea horse is actually a type of fish. Its horse-shaped head gives it its name. This creature lives in the Pacific waters off the west coast of the Americas, from Peru to Southern California. Like many other ocean fish, sea horses face the constant challenge of losing water to their saltier environment. When a Pacific sea horse’s body loses water to its environment, which process is responsible?     endocytosis exocytosis active transport osmosis
