Atlantic Sea Nettle

Jellies Invasion

Jellies live in every ocean, thrive in coastal and open waters, and even live in fresh water. We rarely notice these translucent animals, but they have always been there. Because of recent changes to jellies populations — including massive swarms, voracious eating habits and habitat invasions — jellies are changing the balance of the Earth’s aquatic ecosystems. This stunning exhibit features nine different species of these prehistoric survivors.
