About Pacific Seahorse

Pacific seahorses are medium-sized seahorses with a stocky body and prehensile tail. They display variable coloration including browns, yellows, grays, and reds, often with intricate patterns and leaf-like appendages along the body for camouflage. Males typically develop a brood pouch below the belly for carrying eggs.
