Sierra Leone | Expedition to NP discovers 2 crab species new to science & 2 more not seen in decades

On a recent expedition to the remote forests of Sierra Leone, West Africa, researchers found two species of crabs new to science and rediscovered two species not seen in more than half a century.

For 23 days, Pierre A. Mvogo Ndongo, a researcher from the University of Douala in Cameroon, trekked through remote rainforests in search of the Sierra Leone crab (Afrithelphusa leonensis), a unique purple-clawed land crab that has not been spotted by scientists since 1955.
