Scientists have recently just made a new rediscovery! The Afzelius crab, a crab species found in Sierra Leone has not been recorded since 1796! This species has orange legs with a rainbow-colored shell. Pierre A Mvogo Ndongo and his team discovered the land-dwelling species after only having one clue, “Sierra Leone”.
“These discoveries are bittersweet because the joy of discovering lost species is mixed with the realization that, while not extinct, they’re on the edge of extinction, and that urgent conservation interventions will be required to protect these species in the long term,” says Neil Cumberlidge, a professor in the Department of Biology at Northern Michigan University, who collaborated with Dr. Mvogo Ndongo on the expedition.
These species of crabs belong to the Afrotropical family, a family of crabs that can breathe air and this has allowed the animals to survive on land, climb trees, and even dig burrows. These land crabs are rare and unique and only 5 species in the world are known to exist. Sierra Leone, Guinea, and Liberia are the only African countries where these crabs can be found.
