Red Crab, Diego Garcia
The island is a haven for several types of crab; hermit crabs overrun the jungle at night. The extremely large 4 kg coconut crab, or "robber crab" is found here. The island hosts birds from many different regions, including Indian Barred Ground Dove (Geopelia striata), Turtle Dove (Streptopelia picturata), Indian Mynah (Acridotheres tristis), Madagascar Fody (Foudia madagascariensis), and imported chickens (Gallus gallus).

All the flora and fauna are protected, and it is even unlawful to be in possession of a dead coconut crab. Hefty fines are levied against violators.
