Amblypygi is an order of Arachnids also known as whip spiders or tailless whip scorpions.

In animals like whip scorpions and whip spiders the first two 'sternites' bearing the book lungs may actually be highly modified opisthosomal limbs.

This rainforest is a great place to find many spider species as well as scorpians and 'whip spiders' and, if you're lucky, the largest spider in the world.

Amblypygids are also known as whip spiders and tailless whip scorpions (not to be confused with whip scorpions that belong to the Arachnid order Thelyphonida).

Members of the Tetrapulmonata include spiders, whip spiders, whip scorpions and Schizomida and, together with trigonotarbids, share characters like two pairs of book lungs and similar mouthparts with fangs operating rather like a pocket knife.

Charinidae is an arachnid family within the order of tailless whip scorpions.

Amblypygids are also known as tailless whip scorpions or cave spiders.

Amblypygi is an order of Arachnids also known as whip spiders or tailless whip scorpions.

Amblypygi - "blunt rump" tailless whip scorpions with front legs modified into whip-like sensory structures as long as 25 cm or more (140 species)

Amblypygids are also known as whip spiders and tailless whip scorpions (not to be confused with whip scorpions that belong to the Arachnid order Thelyphonida).

Large invertebrates like Amblypygi and various predatory spiders also inhabit the cave.

It is composed of Thelyphonida, Schizomida, Amblypygi and Araneae.

Phalangium (harvestmen, Amblypygi, Thelyphonida)

He also produced much taxonomic information on the Opiliones, Solifugae, Amblypygi, Uropygi, and smaller orders of arachnids.

Relationships with other arachnids are obscure, but closest relatives may be the Amblypygi, Thelyphonida and Schizomida of the tetrapulmonate clade.

The pedipalps are distinctly raptorial in Amblypygi, Thelyphonida, Schizomida and some Opiliones belonging to the laniatorid group.

Like the related orders Uropygi, Amblypygi, and Solpugida, the schizomids use only six legs for walking, having modified their first two legs to serve as sensory organs.

Other views include proposals that: scorpions are more closely related to the extinct marine scorpion-like eurypterids than to spiders; spiders and Amblypygi are a monophyletic group.

A pygidium is present in Palpigradi, Amblypygi, Thelyphonida, Schizomida, Ricinulei and in the extinct order Trigonotarbida.

This kind of chelicera occurs in the Liphistiomorphae and Mygalomorphae spiders and in the related orders Amblypygi, Schizomida, Thelyphonida.
