- piece of sleeper / flotsam 1
The two specimens above, one male and one female were found in a hollow in the end of a section of sleeper at Sennen Cove, Penwith, Cornwall, 15.12.11. Both were placed in a saltwater marine aquarum, the male survived one week, the female eighteen months.
Species identified by Jack Sewell and confirmed by Dr. Charles Frensen, Curator of Crustacea at Naturalis.
Planes marinus arrives here on flotsam from the tropics. The crab does not survive here because of the colder waters around our coast. If found they will happily live indoors at room temperature in a saltwater aquarium, and can be fed on live prey or pieces of white fish, shellfish or crab sticks.
