The red land crab (Gecarcinus ruricola) is another species commonly found in large numbers on the base. The work of German researcher Marcus Stensmyr, who has studied land crabs on the Cayman Islands, may inspire more research about Guantanamo's land crabs. Stensmyr and his research team discovered that flies of the species Drosophila endobranchia--which had not been seen since it was discovered in 1966--are actually breeding and living in endemic Caribbean land crabs, who act as willing hosts. Although Stensmyr and his team haven't studied the land crabs at Guantanamo Bay, their findings suggest an avenue for future research at the base.
