When's the last time you saw a sea horse? While they can be seen in captivity (the above photo was taken at the New York Aquarium), they often won't survive outside of their natural world. The problem is, they aren't surviving out there either! According to Newsday, sea horses used to be common sights until their preferred habitat, called eelgrass, was decimated by something called "wasting disease" in the 1930s.
Since then, the sea horse population has been on the decline, but now researchers at a Cornell Cooperative Extension lab are turning things around. The group is breeding sea horses in captivity and hope to place them in local waterways, eventually bringing back the natural population. One sea horse expert says that currently "they're very rare and they're very elusive. We only see a few every year." But now they've "started breeding—like crazy." Kind of like Sea Monkeys?
