Recorded distribution in Britain and IrelandFound around the coasts of the British Isles, most commonly along the east coast of England and Scotland. Also common in the Irish Sea.
HabitatCyanea capillata is pelagic species that can be found washed up on beaches.
- Cyanea capillata has a diameter 30 cm or more.
- Usually yellow brown or red in colour.
- It is easily distinguished by a mass of long, hair-like tentacles.
- There at least 65 tentacles in each of the eight groups of tentacles.
Additional informationYoung Cyanea capillata may be found as early as February in British waters, although the main period of abundance for larger individuals is June to September. This species does occasionally occur in large swarms, largely thought to be due to storms and tides that concentrate individuals together (Russell, 1970). They have a very severe sting that can produce blisters, irritation, and muscular cramp and may even affect respiratory and heart function. Cyanea capillata can still sting long after being stranded on the shore.
