Tailless Whip Scorpion


Arachnids, which also include spiders, ticks, and scorpions, are Amblypygids. Amblypygids, which resemble spiders in appearance, are also known as cave spiders and tailless whip scorpions. Very little is known about this order of arachnids, in part because they are nocturnal and have strange, scary appearances. The recent film Harry Potter and the Goblet of Fire included the Mexican tailless whip-scorpion, an Amblypygid.

Life History of Tailless Whip Scorpion

Males drop a spermatophore on the ground after caressing females with their whip-like front legs. The females then use their gonopores to collect the sperm masses. Females will carry the eggs once they are laid until they hatch, and then they will carry the young for four to six days.

The flattened body of a tailless whipscorpion. It has ten legs, the first of which are extremely long, slender, and whip-like. The strong and spiny pedipalps of this amblyplygid are front arms with pincers designed for sensory and predatory usage. In comparison to other tropical locations, the El Yunque National Forest has whip-scorpions that may grow rather large (19 to 25 inches/48 to 63 centimetres, including legs), presumably because there are no large animal predators on the island. Males are smaller than females in adulthood.

Habits of Tailless Whip Scorpion

Being nocturnal, whip-scorpions only come out at night to hunt and devour their prey. They consume crustaceans, big insects, frogs, and small mammals. With the help of their pedipalps, they catch prey, hold it in place as they kill and consume it with their powerful teeth. They are Arachnids, but since they lack spinnerets—tubular organs that produce silk thread—they cannot spin webs. Whip-scorpions have no venom and are safe for people to handle. When whip-scorpions mate, they bind their pedipalps together to stop the female from killing and devouring the male after the mating is over.

Tailless Whip Scorpion Habitat

At most heights, Amblypygid Tailless whip-scorpions may be found living in caves, fissures, and behind big stones. They are rarely seen by people since they are nocturnal.

What kind of shape is the tailless whip scorpion?

The tailless whip scorpion resembles a hybrid of a spider, a scorpion, and a crab in appearance. It has a wide, flat body, a segmented belly, and several flexible appendages that move with the animal to sweep the ground. From either side of the body, eight legs and two pincers protrude and bend in a loose L-shape. Glistening from the sides and top of the head are eight eyes.

Different tailless whip scorpion species will differ in terms of characteristics like size and colour:

Phrynus marginemaculatus: Has broad, dagger-like pincers and is completely black.
Acanthophrynus coronatus: The body of Acanthophrynus coronatus is dark or brownish, and its hairy legs have an almost fuzzy appearance.
Charon grayi: Given that its front legs may grow to a maximum length of 27 inches, Charon grayi is also known as the “giant whip spider.” This is longer than its body by more than three times!
Damon diadema: One of the rare patterned-marked tailless whip scorpions is Damon diadema. Its colours can range from a light brown to a black-blue, and both its legs and abdomen are striped.

The tailless whip scorpion has how many species?

The tailless whip scorpion family has around 155 different species. Fossilised remains have even led to the discovery of extinct species! Tailless whip scorpions have been around for a while; it’s estimated that they are more than 358 million years old.

What size are tailless whip scorpions?

The species will determine the tailless whip scorpion’s size. They range in size from tiny species with leg spans of about 2 to 3 inches to enormous creatures with leg lengths of 25 to 27 inches.

Are tailless whip scorpions members of the scorpion or spider families?

Due to their morphological similarity and categorization as arachnids, whip scorpions, also known as arthropods, are sometimes mistaken for spiders. These invertebrates, such as spiders and scorpions, have morphological traits in common with other species, which makes it simple to mistake them for different species. Mites, ticks, scorpions, spiders, and daddy longlegs are examples of arachnids.

Are tailless whip scorpions venomous?

When tailless whip scorpions skewer prey with their pincers, the prey is ground and liquefied before being swallowed, a process akin to chewing but different from the bite-like behaviour of its predators.

The life span of a tailless whip scorpion.

In captivity, tailless whip scorpions can live for five to fifteen years.

Although their natural life expectancy is unknown, it is presumably less than that of their aquarium-pampered counterparts!

What consumes a whip scorpion?

Bats, lizards, reptiles, and other insect-eaters can prey on tailless whip scorpions.

How are tailless whip scorpions able to reproduce?

Despite their frightening look, tailoiss whip scorpions have delicate mating and parenting habits. Males engage in a ritualistic wooing process in which they touch each other’s bodies and engage in brief “dances” together. Hours may pass as both sides get ready for the following move. When mating, the male deposits spermatophores on the ground and directs the female to pick them up. The female then lays eggs and nurtures them until they hatch on her back.

How do tailless whip scorpions conduct their hunting?

All of the tailless whip scorpions’ nighttime hunting occurs since they are nocturnal creatures. They are sit-and-wait predators who wait in the shadows for their unwitting prey to approach them. To further their advantage, they will occasionally conceal themselves behind rocks or leaves. The tailless whip scorpion uses a variety of assault strategies once its prey is within reach. One involves making a swift, determined lunge that, in essence, skewers the insect on its pincers before it has a chance to respond.

Tailless Whip Scorpion

What diseases do tailless whip scorpions carry?

No known illnesses are carried by tailless whip scorpions. It is hard to declare that they are disease-free because they are so many different species, but nothing has been identified as of yet.

Can tailless whip scorpions coexist with other species?

Although tailless whip scorpions are solitary by nature, they may coexist in large groups in crowded environments like caves. They won’t fight over territory; they’ll hunt around each other.
When they engage in dominance conflicts, this harmony is the one exception. The winner of a dominance war may even decide to murder and consume the loser; these conflicts may be very fierce!










What areas of the EYNF to search for this animal?

At night, along nature paths, in rocky, boulder-strewn places, especially in caves.
