\”Tailless whip scorpions (often called whip spiders), are scientifically referred to as amblypigids because they belong to the order Amblypigi. They have been given the name tailless whip scorpions because of their lack of a tail (telson). In fact, “amblypigid” means “blunt rump”.
Amblypygids are arachnids. Spiders, scorpions, mites, daddy longlegs and other less well-known groups are their closest living relatives.\”
