Seahorses are truly unique, and not just because of their unusual unique shape. Unlike most other fish, they mate for life. They are among the only animal species on Earth in which the males births the unborn young.
Found in shallow tropical and temperate waters throughout the world, these upright-swimming relatives of the pipefish can range in size from 0.6 inches to 14 inches. Because of their body shape, seahorses are rather inept swimmers and can easily die of exhaustion when caught in stormy seas. They propel themselves by using a small fin on their back that flutters up to 35 times per second. Even smaller fins located near the back of the head are used for steering.
They anchor themselves with their prehensile tails to sea grasses and corals, using their elongated snouts to suck in plankton and small crustaceans that drift by. They graze continually and can consume 3,000 or more brine shrimp per day.
These guys are strange and unique.
