Heterometrus spinifer  Heterometrus spinifer, the asian forest scorpion, giant blue scorpion, or Malaysian black scorpion, is a species of scorpions belonging to the family Scorpionidae. "H. spinifer" can reach a length around . The body is shiny black with gray-green reflections. The pincers are highly developed. It feeds primarily on insects, mainly cockroaches, crickets, and locusts. Its venom can cause very severe pain, disorders of vision, and mild numbness in the affected area, but it is not typically lethal to humans. These scorpions tend to be skittish and defensive, using their large pedipalps (pincers) to attack, more than their tails. This species can be found in Southeast Asia, including Malaysia, Thailand, Cambodia, and Vietnam. Generally, these terrestrial scorpions live in moist forests in the dark undergrowth under logs or other debris, and they burrow into the ground where they hide during the day. The Malaysian black scorpion is commonly kept in the pet trade due to its low venom toxicity  and large size.
