Additional information
Other common names include "curly weed", "amber weed" and ju-ju weed" (Pathmanaban et al., 2005).Alcyonidium diaphanum is responsible for the allergic contact dermatitis, termed 'Dogger Bank Itch', experienced mostly by fishermen and dock workers (Pathmanaban et al., 2005). Although previously not reported from any other fishing grounds around the British Isles (Hayward, 1985), and despite its name, Dogger Bank Itch has also been reported from trawler-men in le Havre, shell fishermen from Cornwall and fixed net fishermen in the eastern English Channel (Pathmanaban et al., 2005).
