The Jumping Pit Viper is another feared venomous snakes that occurs naturally in Costa Rica. They have a skin pattern similar to the Fer-de-lance, hence they might be confused on the field. Since both are dangerous, it is still a safe bet to stay away, whether the individual is one species or the other. The Fer-de-lance can be distinguished by the smaller head and ligher eyes; also the Jumping Pit Viper has solid brown triangles all along the body, while the Fer-de-lance features brown markings that are connected diagonally, but on the inside hey have lighter colors.
In spite of its common name, it is not more common for Jumping Pit Viper to jump on top of their prey than any other viper species. Their venom is very strong, so people are very cautious if they handle them.
