A relatively slow swimmer, the Elasmosaurus hides itself in the darker depths and uses its long neck to ambush schools of fish.

The Elasmosaurus lives its life entirely underwater. But instead of laying eggs like a turtle, it incubates an egg internally!

The Elasmosaurus, one of the best known plesiosaurs, is named after the Greek word elasmos, meaning 'thin plate'.

While early fossils constructions suggested it coiled its neck like a snake, the Elasmosaurus actually holds its neck straight!
