APHOTOMARINE
An educational resource dedicated mainly to the photography
and diversity of marine life that can be found in coastal waters
and intertidal areas of Great Britain and Ireland by David Fenwick.

Three live juvenile specimens were found in crevices on an old Goose barnacle covered fishing buoy found with seven Columbus crabs, Planes minutus, at Top Tieb, Marazion, Cornwall. 26.12.15.
How Phascolosoma (Phascolosoma) granulatum entered the buoy is anyones guess but larval settlement is extremely probable, and this might have happened in Irish waters before making landfall in Cornwall.
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.
