‘Seahorse’ in Greek is ‘hippocampus’ which means bent horse. Because seahorses aren’t very strong, they put their tails around plants, in order not to move. The male can have 200 eggs in his marsupium, and what I find surprising is that the babies that are pumped from the marsupium are completely developed, straight away. Seahorses are found in tropical waters, and make their houses in seaweed and sea grass. What surprises me the most is that seahorses can tolerate a lot of salinity, when they are salt-water fish.
