(Tityus pachyurus) It is one of the most venomous scorpions. The injection of its venom to human body requires hospitalization. The venom is utilized by pharmaceutical industry in medicine production. Unfortunately this scorpion does not reproduce in captivity and companies "harvest" them from the forest. As most scorpions they are active during night. They hunt for cockroaches, beetles or moths (in the picture just after catching one). Adults measure 8-9 cm. This species is found only in Panama, Costa Rica and north Columbia.
