Crab ID required

Any one know what type of crab this is ?

Was caught at Hill river on a bait from the beach

It had sea grass actually growing out of its nose (mouth)

Never seen one before ( it was released unharmed )

Cheers Grant .

Thanks for the input guy's, We all called it a spider crab just because the way it looks , but i thought that name might cover a few species .

'Brooding' Spider Crab

Mon, 2012-03-26 10:50

I'm no crab expert, but I asked our Crustacea Curator Andrew Hosie.  It is Paranaxia serpulifera.  It does not have a common name, but he suggested you could use 'Brooding' Spider Crab because the species is unusual in that it has direct development, brooding its young under the abdomen until they walk out as juveniles.  So, there is no planktonic stage, which most crabs have.  It was thought to be restricted to Australia, but was recently found in West Papua.  They are also called Decorator Crabs because they glue bits of weed, sponge, worm casings etc on their back for camouflage.

Thanks Glenn , i sugested to the guy's it was simular to a Decorator crab . The sea grass was imbedded deep into the snout and appeared to be growing there .
