🚨 ARTHROPOD OF THE DAY 🚨
Tailless Whip Scorpions are spiderlike in appearance.. Due in part to their nocturnal lifestyle and bizarre, frightening appearance, very little is known about this arachnid order. An Amblypygid , the Mexican tailless whip-scorpion was featured in the movie Harry Potter and the Goblet of Fire.
The body of the Tailless whip-scorpion is is flat. It has ten legs, and its first legs are very long, thin and whip-like. This Amblyplygid’s pedipalps (pincer-bearing front arms adapted for sensory and predatory use) are spiny and powerful. Whip-scorpions found in the El Yunque National Forest can be quite large (19 to 25 inches/48 to 63 centimeters, including legs) when compared to those found in other tropical areas, possibly because there are no large mammal predators on the island. Adult females are larger than males.
Whip-scorpions are nocturnal, emerging at night to hunt and kill their prey. They eat frogs, small animals, large insects and crustaceans. They capture prey by seizing and holding it with their pedipalps and then killing and eating it with their strong jaws. Although they are Arachnids, they do not have spinnerets (tubular structures used to secrete silk thread) and therefore do not spin webs. Whip-scorpions do not produce venom and are harmless to humans. Whip-scorpions fasten their pedipalps together when they are mating to prevent the female from killing and eating the male when mating is finished.
