On my hols’ with the kids on the beach at Criccieth and they come over bringing their prize which is a plank of wood covered in shells. To qualify.. stinking and covered in shells. Gwyn my mate who is a good ecologist did not recognise the shells. A bit of digging by Gwyn and he found they’re were from across the atlantic and also lower down from tropic areas. The shells are Lepas anatifera. Interestingly they are the same shells as were found on the wing section of the Airbus MH370 which washed up on Reunion Island. This really is a small world and species migration is only a plank of wood away!
Lepas anatifera has a cosmopolitan distribution and is found in tropical and subtropical seas worldwide. Because it is often attached to objects carried into colder seas by currents, such as theNorth Atlantic Drift, it is often found well away from its place of origin and in waters too cold for it to reproduce. In this way it has been recorded from Norway, the Shetland Islands, the Faeroe Islands, Iceland and Spitsbergen.
