Could somebody help me identify this species of Scaleworm please?
Found in a Cornish mid-shore rockpool.
I haver already commented on this animal on the group pages. Scale worms can be difficult for a specialist to identify with certainty even when he/she has a microscope. Some species are easy enough but most have to be identified with attention to fine detail; you can't do that on a picture. Any ID I gave would have to be an educated guess based on broadly similar worms found elsewhere in SW England, on the colour (which isn't always a good character) and on the 15 pairs of elytra. IDs like that are very risky. If an ID is very important the actual animal has to be seen by a specialist.
