Today’s Exhibit of the Day? The lion’s mane jellyfish (Cyanea capillata). Jelly-ve it or not, this critter is one of the world’s longest animals. This jumbo-sized jelly trails a “mane” of more than 800 stinging tentacles that are covered in cells with venom that stun prey, including other jellyfish, small crustaceans, and zooplankton. Just how long is the lion’s mane jellyfish? Well, its tentacles can grow more than 100 feet (30 meters) long! In fact, the longest examples of this species—which inhabit the Arctic Ocean—are even longer than the longest known blue whale. Come see a life-size model of one at the Museum’s Hall of Biodiversity.
