Sea Urchin Carrying Crab - Dorippe frascone This Sea Urchin Carrying Crab - Dorippe frascone has a symbiotic relationship with a long-spined sea urchin and carries one around on its carapace by using 2 of its legs.  The Crab uses the Sea Urchin as protection and the Sea Urchin benefits from the crab by getting some of its food from the food that the Crab eats as the Crabs are messy eaters.<br />

It is always fun seeing the Crab moving around carrying the Sea Urchin.  Usually during day time, the crab is buried in the sand. Anilao,Batangas,Crab,Dorippe frascone,Geotagged,Philippines,Sea Urchin Carrying Crab,Summer Click/tap to enlarge PromotedSpecies introCountry intro

  1. What an absolute highlight, Albert! Hilarious, interesting, and an incredibly detailed capture.
    It makes me wonder how such an initial relation starts..."need a ride?"

    1. I just saw this guy profiled on a PBS nature program about a week ago -it said they pick the urchins up and carry them around for protection :p - nothing tries to get them so long as they keep those poisonous urchin spines pointing up. The poor urchin apparently doesn't get much out of the deal, beside a ride to somewhere they may or may not want to go.... Posted 2 years ago
      1. lol yeah, I can imagine it not being entirely voluntary. Still better than this though:

        1. Thanks, Ferdy and morpheme for your kind comments :)

          Wildlife is so amazing especially when you get to observes their behaviours and antics :D
          A few days ago, I was walking along a road in the outskirt, mostly looking for butterflies when it started to rain/drizzle and I decided to turn back. I passed some bushes and saw something like a twig on a plant with big leafs, decided to take a second look and low and behold, it was a baby Snake! What's amazing about this encounter was because of the rain and small drops of water on the leafs, this baby Snake came out to the open to drink the water droplets. It was an amazing experience for me :)

  2. Interesting to show your other recent photo where it is the urchin being the chief:

    Magnificent Fire Urchin - Asthenosom varium The Asthenosoma varium is called Fire Urchin for the red colours associating it with fire but also for the intense pain if stung by them.<br />

Some Crustaceans lives commensally with them and in the picture, a small Zebra Crab can be seen on it. Anilao,Asthenosoma varium,Asthenosoma varium (Fire Urchin),Batangas,Fire Urchin,Geotagged,Philippines,Sea Urchin,Summer

    1. Thanks for sharing this other pic here, Ferdy.
      Although in this instance, the Sea Urchin looks like the 'chief' its actually the crab that determines which Sea Urchin it wants to build its 'home'. Usually the crab settled on the Sea Urchin permanently, making it its home by cutting away some of the spines and mostly staying on the 'bald patch'. They also gets protection by living on the Sea Urchin. When the time comes to feed, they crawled to the underside of the Sea Urchin to scavenge the sea bottom for food.

''Dorippe frascone'', the urchin crab or carrier crab, is a small species of crab in the family Dorippidae that was first described scientifically by J.F.W. Herbst, in 1785. It is found in the Red Sea and parts of the western and eastern Indian Ocean. It often has a symbiotic relationship with a long-spined sea urchin and carries one around on its carapace.
