Sea horses and sea dragons are fascinating creatures that gracefully float above the sea floor, grabbing seagrass with their tails and feeding on small crustaceans. They are actually fish with a uniquely shaped body covered with bony plates that actually make them rather slow. More than 200 species of seahorses, sea dragons and pipefish make up the Syngnathidae family. Their name comes from the greek word syn (together) and gnathus (jaw), which means that their upper and lower jaw have fused, that makes sucking up their prey far easier. The shape of their mouth is not the only interesting feature; the ability of males to incubate fertilized eggs is also noted.
