Here's a breakdown of why:
* Blending In: Seahorses are incredibly good at blending in with their surroundings. They use their skin color and texture to match the coral reefs, seaweed, and other aquatic plants they live near. This makes it harder for predators to spot them.
* Staying Put: Seahorses are poor swimmers, so they need a way to stay in one place without being swept away by currents. By anchoring themselves to coral, they can conserve energy and avoid getting lost.
* Finding Food: Seahorses are also ambush predators, meaning they wait for prey to come to them. By staying still and camouflaged near coral, they increase their chances of catching small crustaceans and plankton that pass by.
While they don't hang on in the traditional sense, they use the coral's structure for crucial survival needs!
