Hydra facts: not the mythical beast! | Animal Fact Files

The word hydra might bring up images of a multi-headed beast from Greek mythology, but it's also the name of real life animals! Hydras are hydrozoans who don't form colonies.

They can, however, be eaten or perish under harsh conditions. Let's learn more about these amazing animals! Scientific Name: Genus - Hydra Range: cosmopolitan Size: less than an inch (2.54cm) Diet: crustaceans, fish and insect larvae Lifespan: limitless!
