Seahorses are found in tropical waters, like the Indian Ocean, the Caribbean, the Mediterranean, and the warm parts and west parts of the Atlantic. The latitude is about fifty degrees south and fifty degrees north. Their homes are in seaweed and eel grass. They wait a long time to eat their prey. When they eat, they suck and make slurping sounds with the suction. They eat fish larva, plankton, water insects, and daphnia. They stay in shallow water with lots of seaweed. Where they live, there is vegetation, the coral reef, coastal lines, in mangroves, and in the subtropical. A seahorse holds its habitat (plants, rocks…) in order to stay in place. A few species like the seahorse of South Africa, can be found in estuaries, and can tolerate a lot of salinity, but with the risk of dying in a freshwater flood. There are eleven types of seahorses in Australian waters. ‘Hippocampus zosterae’ lives in the Gulf of Mexico, and ‘Hippocampus injens’ lives in Baja California - Ecuador. The dangers to the habitat of seahorses are pollution, destroyed grass fields, and developed marinas.
