How many species are there?
Counting the number of kinds (species) of seahorses has been nothing short of a nightmare for scientists. While hundreds of different names have been given to seahorses, scientists recognize 32 different species. Many seahorses are able to dramatically change colors and body shape. For this reason, scientists often believed they were encountering different species, when in fact, they were often naming species more than once with different names. How confusing--just imagine if your friends were given different names every time they changed clothes!
