Seahorses are a genus (Hippocampus) of fish belonging to the family Syngnathidae, which also includes pipefish and leafy sea dragons. There are over 32 species of seahorse, mainly found in tropical and subtropical coastal and reef waters all over Pacific, Atlantic and Indian oceans. From North America down to South America there are approximately four species, ranging from very small in size (dwarf seahorses are only about an inch long) to those much larger, found off the Pacific Coast of Central America (which get to be about a foot long, called the Hippocampus ingens). Found in the Caribbeanís coral reefs are Hippocampus reidi, which are large slender seahorses that turn fluorescent neon colors when they dance. The Hippocampus erectus are bigger and fatter seahorses found anywhere from Nova Scotia down to around Uruguay. These fish stick to narrow zones, with males staying in about one square meter of their habitat while females range about one hundred times that area. They bob around in sea grass meadows, mangrove stands, and coral reefs where they are camouflaged by murky brown and grey patterns that blend into the sea grass backgrounds. During social moments or in unusual surroundings, seahorses turn bright colors. According to co-founder of Project Seahorse, Amanda J. Vincent, mates can blush a shade of creamy yellow when meeting each other in the morning. She even encountered one male who took the shade of the orange tape she used to mark the grid in the study area.
