Phryna grossetaitai Amblypygi Tropical Giant Arachnida Whip Spider or Tailless Whip Scorpion Phrynidae, cephalothorax cm 3-3.5 (legs and pedipalps not included in measure), leg span of 20 cm approximately.
Order: Amblypygi (Tailless Whip Scorpions), family: Phrynidae.
Common name: Whip Spider or Tailless Whip Scorpion.

Amblypygi are an order of chelicerate arachnid arthropods also known as whip spiders or tailless whip scorpions. The name means "blunt tail", a reference to the lack of the flagellum otherwise seen in typical whip scorpions. However they are neither scorpions nor spiders, from which they differ considerably.
These arachnids are stingless, possess no poisonous silk glands or fangs, and rarely bite when threatened, but can grip fingers with their pedipalps, causing thorn-like puncture wounds.
Amblypygids have a large cephalothorax, a flattened body and lack a caudal appendage. The raptorial pedipalps can be of two shapes: short and stocky or long and thin, in any case suitable for predation, they are sharp, thorny, composed of six segments, used to grasp and hold the prey which is eaten by the chelicherae, jaws composed of two segments, placed on the cephalothorax between the pedipalps. They have four pairs of eyes, one median and three lateral pairs, four pairs of legs of which the front pair, very long and thin, has evolved into a sense organ used as antennas. The life of the Amblypygids takes place at night, they prey on other arthropods. The chicks of Amblypygids as soon as they hatch from the eggs find themselves in a ventral pocket in the abdomen of the female and then assume the same behavior of the scorpions climbing on the mother's back.
In 2016, 5 families, 17 genera and about 155 species were discovered and described. They are found in tropical and subtropical regions worldwide, mostly in warm, humid environments and like to remain protected and hidden within leaf litter, caves or under bark. Some species are subterranean; they are all nocturnal. Fossilized Amblypigids have been found dating back to the Carboniferous period, such as Weygoldtina.
