Seahorses are famous fish, much appreciated for their beauty and gracefulness. They swim in an unusual way, keeping upright and only moving their dorsal fin to propel themselves forward.
They feed on small molluscs, worms, crustaceans, and plankton that they suck in through their tubular snout.
There are about 25 species of seahorses, living in brackish and salty waters of the Atlantic, Indian and Pacific Oceans, usually in shallow areas with plenty of vegetation. By wrapping their prehensile tails around seaweed and marine plants, seahorses remain practically immobile in an upright position, going unnoticed by potential predators.
This camouflage is strengthened by their ability to mimic, i.e. to change colour and acquire a tone similar to that of their environment.
