May 3, 2010 : Lion's Mane Jellyfish

Lion's Mane Jellyfish

The lion's mane jellyfish (Cyanea capillata) is the largest known species of jellyfish. Its range is confined to cold, boreal waters of the Arctic, northern Atlantic and northern Pacific Oceans, seldom found farther south than 42°N latitude. Similar jellyfish (which may be the same species) are known from the seas off Australia and New Zealand. The Arctic Lion's mane jellyfish is one of the longest known animals; the largest recorded specimen had a bell (body) with a diameter of 2.3 m (7 feet 6 inches) and tentacles 36.5 m (120 feet) long. It was found washed up on the shore of Massachusetts Bay in 1870. This specimen was longer than a blue whale, generally regarded as the largest animal on earth.
