A left-handed hermit

Ciliopagurus caparti belongs to the group of hermit crabs that is sometimes called left- handed because the left claw is larger than the right, as opposed to the situation in other hermit crabs. C. caparti was originally described as a new genus Trizopagurus. The original description in Bulletin, Institut Royal des Sciences Naturelles de Belgique, 28(39): 1–8 is available for download from ATOL:Decapoda. We hope that our just submitted samples will yield DNA-barcodes of the species in the BOLD database.

Portrait of a crab

Sakaila africana was recognized as a new species by Raymond B. Manning and L.B. Holthuis in 1981. Their publication in The Smithsonian Contributions to Zoology is an important source  to the identification of West African crabs. An electronic version of the publication is available on this link. Our workshop found Sakaila africana in samples from Guinea Conakry.

Environmental monitoring in Ghana

On 10th July, the workshop was visited by guests from the Norwegian Institute of Marine Research who are doing field work in Africa from R/V Dr Fridtjof Nansen. Tor Ensrud gave a presentation of monitoring activities performed from the Nansen in Ghanaean waters. He showed pictures and impressive video clips from the prototype of a sampling rig equipped with ROV and 3-5 grabs. Some of the pictures can be seen at the IMR website.
