Lion's Mane Jellyfish Cyanea capillata

BACK TO ... .........

Description The lion's mane jellyfish (Cyanea capillata), also known as hair jelly,[1] is the largest known species of jellyfish. Its range is confined to cold, boreal waters

Capable of a bell diameter of over 2 metres (6 ft 7 in), these jellyfish can vary greatly in size; those found in lower latitudes are much smaller than their far northern counterparts with bell about 50 centimetres (20 in) in diameter. The tentacles of larger specimens may trail as long as 30 m (100 ft) or more. These extremely sticky tentacles are grouped into eight clusters, each cluster containing over 100 tentacles, arranged in a series of rows.

Habitat A coldwater jellyfish which does not cope with warmer waters. The jellyfish are pelagic for most of their lives but tend to settle in shallow, sheltered bays towards the end of their one-year lifespan
