sealord > The Columbus crab, Planes minutus, was given to me by Guernsey commercial fisherman Chris Marquis on 14 December 2006.  He found the crab living on a buoy covered in goose barnacles, which was floating near Herm and Sark in the Bailiwick of Guernsey.  This crab was photographed hanging upside down on a cuttlebone.  The crab likes to float near the water's surface and becomes distressed if it accidentally falls off its float.

sealord > This Columbus crab, Planes minutus, was given to me by Guernsey commercial crab fisherman, Chris Marquis, who found it on a float covered with goose barnacles, Lepas anatifera, on 14 December 2006 near the islands of Herm and Sark in the Bailiwick of Guernsey. This individual was similarly coloured to Columbus crabs washed up on the south coast of England at the same time.  This colour pattern differs to Columbus crabs that had arrived in Guernsey waters in previous years.  This individual was photographed on a floating cuttlebone.

sealord > This Columbus crab, Planes minutus, was given to me by Guernsey crab fisherman, Chris Marquis.  He found it on a goose barnacle, Lepas anatifera, covered buoy in the Big Russell - the passage between the islands of Herm and Sark in the Bailiwick of Guernsey.

I photographed the Columbus crab on a rubber Kito sandal, size 44, I found washed up on the strand-line on Guernsey's north-east coast on 23 December 2006. This scandal was covered in small goose barnacles. The crab lived in the scandal in an aquarium for a number of days before the barnacles began to die.  The crab is now living on a foam mat.  

Columbus crabs, also known as turtle, sargassum or Gulf weed crabs, live on flotsam or under the shells of turtles in the North Atlantic and other oceans.  They arrive in Guernsey waters with the prevailing currents in the later part of the year.  On the same day Chris Marquis found this Columbus crab about twenty Columbus crabs were found on the south coast of England.
