Eat any small animal they can capture
- Scorpions are opportunistic predators that eat any small animal they can capture. Common prey includes insects as well as spiders and other arachnids, including other scorpions. Less-common but regular prey includes pill bug s, snails, and small vertebrates such as lizards, snakes, and rodents.

Sep 4, 2023 · This segmented body allows scorpions to move with precision and agility, making them formidable predators. One of the most fascinating aspects of scorpions is their ability to fluoresce under ultraviolet light. This intriguing phenomenon, known as biofluorescence, has puzzled scientists for years.

scorpion, (order Scorpiones or Scorpionida), any of approximately 1,500 elongated arachnid species characterized by a segmented curved tail tipped with a venomous stinger at the rear of the body and a pair of grasping pincers at the front. Although scorpions are most common and diverse in deserts, they also live in many other habitats. Primarily no...
Scorpions are relatively large among terrestrial arthropods, with an average size of about 6 cm (2.5 inches). Scorpions exhibit few sexual differences, although males usually are more slender and have longer tails than females. Giants among scorpions include the black emperor scorpion (Pandinus imperator), an African species found in Guinea, which ...
In addition to desert habitats, scorpions have adapted to temperate, subtropical, and tropical environments such as grasslands, savannas, and forests. They live on all major landmasses except Greenland and Antarctica. Their range extends from Canada and central Europe to the southern tips of South America (Tierra del Fuego) and Africa, and they hav...
Breeding is seasonal and generally occurs during the warm months, ranging from late spring through early fall. Males may travel hundreds of metres to find receptive females. It appears that males find females by localizing a pheromone that the female emits from the end of her abdomen. Mating in scorpions is preceded by a complicated and characteristic courtship initiated by the male. He first faces and grasps the female, using his pincers (pedipalps). Then the pair, directed by the male, moves sideways and backward in a dancelike motion called promenade à deux. These actions result from the efforts of the pair to find a smooth surface on which the male can extrude a glandular secretion that forms a stalk to which the spermatophore (sperm-containing structure) is attached. He then maneuvers the female so that her genital opening contacts the spermatophore. Once she is positioned over the spermatophore, physical contact with it causes spermatozoa to be ejected into the genital opening (gonopore) of the female. Males that remain near females after mating are sometimes killed and eaten.

In general, females mate multiple times. In some species, mating must occur after each clutch of offspring is produced in order to fertilize another clutch of eggs. In others, multiple clutches of offspring can be produced from the sperm stored from a single mating. There are at least two species known that can produce offspring without mating at all (parthenogenesis).
The mother invests a great amount of time and energy in her offspring. Unlike most nonmammalian animals, scorpions are viviparous, giving birth to live young instead of laying eggs. Once fertilized, the eggs are retained in the female’s body, where the embryos are nourished in utero for periods varying from several months to a year. The birth process itself may last from several hours to several days. Temperate species usually give birth in spring and summer, whereas tropical species give birth throughout the year. Litter size averages 25, with a range of 1 to more than 100.

Scorpions are opportunistic predators that eat any small animal they can capture. Common prey includes insects as well as spiders and other arachnids, including other scorpions. Less-common but regular prey includes pill bugs, snails, and small vertebrates such as lizards, snakes, and rodents. The only known specialist scorpion is the Australian spiral burrow, or spider-hunting, scorpion (Isometroides vescus), which feeds solely on burrowing spiders.
Most scorpions are sit-and-wait predators that remain motionless until a suitable victim has moved into an ambush zone. Scorpions can sense tiny ground vibrations, and some can detect airborne vibrations of flying insects. These behaviours are sophisticated to the extent that scorpions can determine the precise distance and direction of their prey. Once the prey has been detected, the scorpion turns, runs to the prey, and seizes it. The prey is stung if it is relatively large, aggressive, or active. Otherwise it is simply held by the pedipalps as it is eaten. Many of the thick-tailed scorpions (family Buthidae), however, actively search for prey. These species usually have long, slender bodies and pincers (chelae). Many have powerful venoms to compensate for their small pincers.
Today, scorpions use book lungs to breathe, a type of breathing organ also used by some spiders and very similar to gills. Scorpions are numerous in many regions but are rarely seen, due to their nocturnal and secretive nature. Even so, many cultures have myths involving scorpions and their powers.

Dec 23, 2009 · The needle part of the telson is called the aculeus. It is similar to a hypodermic needle. Each venom sac is connected to the openings of the venom duct on the aculeus. The venom sacs are controlled voluntarily, so the scorpion can regulate how much venom is injected.

Scorpions serve a vital role in the ecosystem eating small animals and are an important source of prey for larger animals. Areas with a high population of scorpions see them serve an important role in the food web by helping to control the insect population.
