We recorded the incidence of predation on snakes by the amphibious freshwater land crab Eudaniela garmani (manicou crab) in the rainforests of the Caribbean island of Tobago during 168 days of field observation (spanning a 4-year period) conducted between the hours of 08.00 AM and 12.00 noon and 21.00 PM and 23.30 PM. Six instances of manicou crabs eating snakes were observed and photographed. Field notes are given for each predation event, and photographs are presented for three of these: clouded slug-eating snake, Sibon nebulata nebulata, three-lined snake, Atractus trilineatus, and vine snake, Oxybelis aeneus. We conclude that the potential predation pressure placed on local snake populations by manicou crabs merits investigation.
