Camo-crabs! So cool...and, smart too - don't hydroids have stinging cells? So, this is camo and defense. Posted 7 years ago

  Yes, Christine. You are right.
  Hydroids can stings, so it serves as double purpose to the Crab, camouflage and defense. Posted 7 years ago

Hello Albert, this is not Hyastenus but Achaeus spinosus. See ressemblance here:
https://en.wikipedia.org/wiki/Achaeus_spinosus
the rostrum is thicker in Hyastenum bispinosus. See here:

I have removed it from Hyastenum bispinosus. Posted 4 years ago, modified 4 years ago
