Hi, can anybody identify any of these? All found in the mouths of Whiting caught off the brighton marina, so they do look a little mangled.

Fish seems to be a clingfish but dont know which species.
My guess would be Connemara Clingfish.

Stomatapod - not sure which species. Seems to be only 2 species in british waters, Platysquilla eusebia and Rissoides desmaresti, but cant find much info about them. From the pictures, I cant count the number of spikes in the claws.

Don't have a clue which species of prawn or squat lobster the other two are.

Ohh interesting!

The cling fish does look a bit mangled, It's not the common one I usually see Liparis liparis as the eye's are too big, I have a book at work which would help so I might check on Monday.

The Stomatapod is very cool, I don't often see these and the one you have in the picture looks like a juvenile by the size of it. I would say it's most likely to be Meiosquilla desmaresti as it appears to have a bilobal cornea (the other species Platysquilla eusebia has a broad cornea, although not bilobed). But it would be best to check the number of spines on the claw to be sure.

The squat lobster is very hard to be sure on, from what I can see in the picture I think it's most likely to belong to the genus Galathea but you'd need to check some bits down a dissecting microscope to be sure on the species, and I wouldn't be at all surprised if it was a different family/genus on closer inspection.
A link to a key if you still have the specimen British Galatheiodea

The prawn is a hard one too, from the looks of it (the short small rostrum and the claws) I think it is most likely to belong to the genus Processa but like the squat lobster a closer look would be needed and I wouldn't be surprised if I was wrong about the genus.

Hope it helps, sorry I couldn't be more specific.

UPDATE:

I've taken some closeups of the claws, Im going to go with M. desmaresti now. Check these images out. Looks like 5 spines.
I was quite excited when I found it, I didn't even know that stomatapods existed in britain at all. First thought it was an amphipod, but realised that it was something different.

Just wondering, what are the bristles behind of the claws in the images? Couldn't see them with the naked eye? Looks like its forms a slot for the claw to close into.

I do have the specimens of the crustaceans, but they are well dried out now.

Thanks for the link to the key, Ill give it a try later.

Yes it definitely looks like it has only 5 spines. The bristles and small spines behind the claw will help it grip any prey it manages to spear with its claw, and the indentations for the spines to close into is quite common in crustaceans.

They aren't very common in British waters and I think most people wouldn't expect to find them, I've had colleagues that think they've found an invasive species when they've come across them!

Hello,

really good pics.

I suggest the clingfish is

Apletodon dentatus
