Central American coral snake (Micrurus nigrocinctus). It is highly venomous snake from the family Elapidae. As most snakes from the family it is active at night time, hunting for other snakes, lizards and amphibians. Despite strong neurotoxins in its venom it is very shy and fearful of people and avoids human contact. It moves mainly on the forest leaf litter and can gain significant speed. Once in the jungle, in the middle of a night I learned it myself as I tried to catch it up and photograph. I managed to do it, only because the snake slithered up a small bush and then continued up the hill.
