Images of this species were very kindly supplied by Chris Rickard for the purpose of displaying this important and rarely seen species on APHOTOMARINE. The species is unique among British foraminiferans and has been referred to as 'giant foraminifera', it is a very large foram indeed at approximately 18-40 mm diameter.
This large and rare species is only found in the bottom of sea lochs on the west coast of Scotland, at a depth of between 10-30m, so is only observed by diving. The species has been obseved in lochs such as Loch Torridon, Loch Linnhe and Loch Duich. This species is usually found covered in sediment, so can be very tricky to spot.
The images are strictly ©Chis Rickard and may not be commercially used copied without his express permission.
Chris has numerous images of this species, the ones above were chosen by use here to give people an idea of what this species looks like in-situ, both covered and uncovered.
