Coryphella browni Picton, 1980
Fjordia browni (Picton, 1980)
Distribution and status
Iceland to Atlantic France (GBIF map). Common around Ireland and Britain where Tubularia occurs, but less common in North Sea (interactive UK distribution map). May extend further, but late recognition of species makes re-examination of Iberian and Western Mediterranean specimens necessary.
Ecology and behaviour
Similar species
- Coryphella lineata (Lovén, 1846) - White lines run along dorsum and sides of body, and the full lengths of the rhinophores and oral tentacles.
- Coryphella gracilis (Alder & Hancock, 1844) - Distal white ring on cerata narrower than on C. browni. Maximum size 15 mm.
- Coryphella verrucosa (M. Sars, 1829) - Interrupted white dorsal line on body becomes continuous on tail. Distal white ring on cerata narrower than on C. browni.
- Flabellina pellucida (Alder & Hancock, 1843) - White pigment covers distal end, including apex, of cerata.
Key identification features
- Excluding appendages, the only surface pigment on the body is the interrupted white medial line from the rear cerata to tip of the tail.
- Broad white ring on cerata distally, but no pigment on apex [4].
