Specimens found in galleries under Lithothamnion sheets on rocks and bedrock of the middleshore at Gyllyngvase, Falmouth, Cornwall. 18.06.15.

In natural light the species appears a very dark bottle green colour. A dark green cirratlid was discovered at Gyllyngvase in 1846 by Dr. W.P. Cocks. More recently Dodecaceria concharum has ben recorded by Roger Bamber close-by at Castle Beach, Falmouth. Confusion surrounds the identity of Dodecaceria species in the UK, it has been suggested to leave as Dodecaceria sp. for purpose of recording.

The main objective of this website is in furthering environmental awareness and education through the medium of photography. To increase awareness and access to the wildlife of the region and help

people find and identify it. Sometimes the difference between species is obvious but many species can only be determined by observing microscopic characteristics that are specific to any one species.
