Approx. 45mm Long. I always assumed this was a Sea Slater (Ligia Ocianica), however, the tail isn't right.
No interactions present.
This does not look like the sea slater which is generally grey and has a smaller width to length ratio than the beast in your photo. The sea slater has very obvious 'tails' x4 (the uropods) which are not obvious in your pics.
The rear section of the sea slater (the pleon) is segmented and articulated which is certainly not obvious in your animal.
Thanks, Mike. It is good to learn something new each day!

I've never encountered this group of animals either, and it's an impressive looking beast - something else to add to my wildlife sighting wishlist!
