Just noticed this observation, I saved the image and closed in on the head end, if I'm not mistaken I can see the paddle like structures on this one also.
Can you tell me how it is IDed as P. serratus so that I will know what to look for in my own pics?
I should have posted the 2nd pic, where you can just about see the upcurved rostrum.
...also be P.adspersus which has slight upward curvature - really need to look at underneath of rostrum - P.adspersus has 4 grouped serrations 2nd just under 1st. P.serratus has 4/5 in a line.
I'm picking up only pointed end to rostrum - so I'm leaning towards P.squilla now if there is no upturn to the rostrum?
My ID is based on Collins guide'96 (P..Hayward etc) which has good side-on illustrns of the 6 sp's like P.elegans plus descriptions; & I find the illustrns well corroborated by EOL or google images. It shows P. elegans & P. adspersus with short rostra & photos in EOL & Google images show they dont extend much beyond where the forward antennae branch,whilst in my prawn the rostrum extends beyond that pt a distance = to that between eyes & branching pt.
Even though nrly straight on I'm clear it's upcurved (& not sideways!) & with sharp slender tip, which distinguishes it from P. longirostris
P.squilla is a bit of a curved ball; not in my Collins, in WoRMS (=marinespecies.org) it's unaccepted & a synonym for P.adspersus & in EOL it's either that or P.elegans.
I agree it's a bad way to photo prawns for ID.(& you might be right about the beachcombercoconut prawn gramandy).
I hope that explains some of my devious methods, Cathal. I've also found a site which lists uk species (which is under construction & seems not to go above families, eg http://www.nhm.ac.uk/research-curation/scientific-resources/biodiversity... & you then click on members of palimonidae.
There seems to be quite a bit more to prawn IDing than I had thought. So far I have believed all the prawns I have seen to be P. serratus but I need to look closer. Thank for posting the above info Chris.
