Science can be cool: Glaucus atlanticus

Some science (and other educational things) is really interesting to me and I want to share really cool facts, pictures, and stories sometimes.

For example, this little guy is a species of sea slug called the Glaucus Atlanticus.It grows to around 35 mm. It earns the name that sounds like Atlantis because it looks a little like a mythical water dragon. \(^-^)/
They float partially with an air bubble, which they swallow and store in their gastric cavity. It's just so cute! But they also have a rather unique defense mechanism. They store the nematocysts produced by jellyfish (their prey) in their own tissues to protect against predators with a weaker version of the jellyfish's sting.That sting of these creatures can sometimes be felt by a human.
