Lion’s Mane Jellyfish Cyanea capillata

Jellyfish is the common name for many species of what scientists refer to as cnidarians (pronounced with a silent ‘c’).  The root of cnidaria is ‘nettle’ in Greek which refers to the stinging tentacles of some species. There are two types of cnidarians: the Hydrozoa and the Scyphozoa. The largest scyphozoan in the North Pacific is the lion’s mane jelly. Large specimens can exceed 2 m in diameter with 9 m long tentacles. It is often abundant in coastal waters in late summer. The tentacles can give a nasty sting so it is best to leave this animal alone. Meat tenderizer is supposedly a good antidote of stings. Stranded jellies look like blobs of gelatinous mass on the beach but in the water they are graceful creatures. The lion’s mane jelly is a pelagic species is found from Mexico to Alaska. It eats plankton caught in the mesh of trailing tentacles which are drawn up to the mouth under the bell. Jellyfish are eaten by sea turtles. The video shows how the animal moves in water.
