The Hispaniolan Giant Tarantula (Phormictopus cancerides) is a tarantula native to the Dominican Republic, where it is called Cacata; Haiti, where it is called Araignée-crab; and Cuba, where it is rare. It occurs from the West Indies to Brazil. During the day they hide under rocks and debris and come out at night to look for prey. Their fangs are quite formidable at more than 2 centimeters long, and when they pierce the body of a victim, venom is injected which paralyzes and breaks down the body tissue of the prey, allowing the tarantula to suck up the liquified insides. Its bite is not harmful to humans but can cause irritation and swelling.
