The Seahorse is characterised by his upright posture, segmented body, horse-like face and prehensile tail. There are 54 species spread across the world, varying in colour and number of body rings. Seahorse swim vertically and are weak swimmers, using their dorsal fin and pectoral fins to steer. The Pygmy Seahorse is the slowest moving fish in the world. Because of this, he spends much of his time anchored to a stationary object. His long snout acts as a vacuum, sucking small crustaceans from the water. Fertilzation is external, with the eggs implanted into the male's pouch, where they are incubated and nourished until they hatch and he gives birth.
