Macropodia deflexa

Forest, 1978


Penny Martin Plesae could you advise which crab this is? Thank you .

Bernard Picton There are two genera of small spider crabs in our area, Penny. Inachus and Macropodia. This is a Macropodia, but I don't think it's possible to distinguish them without detailed examination of the rostrum and antennae.

Bernard Picton Macropodia Leach, 1814 Macropodia deflexa Forest, 1978 Macropodia linaresi Forest & Z Alvarez, 1964 Macropodia rostrata (Linnaeus, 1761) Macropodia tenuirostris (Leach, 1814)

Bernard Picton Macropodia rostrata seems to be the commonest one.

Andy Horton I think this is Macropodia

Becky Hitchin Don't Inachus more often have sponges attached to them than Macropodia? Or is that just a local thiing down here?

Becky Hitchin Of course, always one that proves the rule!

Bernard Picton There are three Inachus species in Britain and Ireland, I think they all tend to have sponges on them, whilst Macropodia decorates itself with weeds and hydroids.

Penny Martin Thank you ..... lots seen on this dive and they all looked slightly different .... some much chunkier than others and many covered with seaweed !

Ian Macleod Hi Penny. They are like us, they change as they grow up !! Lolololol. Ian In a message dated 12/02/2012 18:26:48 GMT Standard Time,

Andy Horton It might not be fully grown, but it is not a baby. They do not grow all that large.
