"Amblypygi is an order of invertebrate animals belonging to the class Arachnida, in the subphylum Chelicerata of the phylum Arthropoda.
Amblypygids are also known as tailless whip scorpions (see also whip scorpion). The name "amblypygid" means "blunt rump", a reference to a lack of the telson ("tail") carried by related species.
As of 2002, approximately 5 families, 17 genera and 136 species have been described. They are found in tropical and subtropical regions worldwide. Some species are subterranean; many are nocturnal. During the day, they may hide under logs, bark, stones, or leaves. They prefer a humid environment."
