Specimen above found in rock crevice on the lowershore at Long Rock, Penzance, Cornwall. 23.08.13.
Sipunculans are extremely difficult to identify, and almost impossible to identify using external characteristics alone. The siphunculan species here was identified by dissection, by Dr. Paul Gainey. It was keyed out using the worms internal and external features. This was very necessary because there are very few records of this species in England; the species mainly being recorded from the West Coast of Scotland and Ireland.
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.
