Scorpions Are Predators With a Sensitive Side | Deep Look

Look past their grasping claws and lightning-fast stingers, and you'll see scorpions have a delicate pair of comb-like organs on their belly called pectines. These sensory body parts help them navigate, and figure out who's a menace, a meal or a mate.

Scorpions are arachnids with a monstrous reputation, but wait until you get to know their sensitive side. On their belly-sides, scorpions sport unique, brush-like organs called pectines, that endow them with extraordinary sensing abilities. These sensors help the animals with a variety of behaviors: finding mates; hunting prey; identifying other scorpions or predators; and they even help them navigate.

Each pecten resembles a small comb, and each scorpion has a pair. These brush lightly over the ground as the animal walks. The comb structures contain an overlapping series of flexible teeth that make contact with whatever surface a scorpion walks on. Zooming into a microscopic level, each tooth is covered in special sensory cells called peg sensilla that enable them to be extremely sensitive to chemicals and physical vibrations. There can be over 100,000 peg sensilla on each scorpion. Each peg sensilla is connected to the animal’s brain by about a dozen nerve cells. The animals read their environment by the detailed chemical and physical cues picked up through tiny pores on the tips of the peg sensilla.
--- How do scorpions reproduce?
The female scorpion will release pheromones, which are picked up by a male scorpion, using his pectines. The pair then performs a kind of dance called the “promenade a deux” (French for “walk for two”) where they grasp each other’s claws and mouthparts. During the “dance” the male deposits a spermatophore - a structure that contains a packet of sperm - on the ground. He leads the female over the spermatophore, and she picks up the sperm packet to fertilize her eggs. Gestation can last over a year for some species, and unlike most arachnids, the female scorpion gives birth to live young. She even carries the offspring on her back for some time before their first molt.
--- Where do scorpions live?
Scorpions do prefer arid or semi-arid habitats like deserts, but they have adapted to live in a wide range of environments, including high mountainous regions, subtropical forests and intertidal zones. They can be found on all continents except for Antarctica. The Western forest scorpions (Uroctonus mordax) featured in this episode of Deep Look were found in a temperate forest in Oakland, California.
--- How dangerous are scorpions to humans?
A vast majority of the world’s more than 2500 species of scorpions are not a serious threat to humans. Only 25 species are known to have venom capable of killing a human.

    Great video and a truly deep look as always; the glowing scorpion at 3:04min is just jaw-dropping!
    We also love the Q&A in your description. It's quite inspiring, not only for your community but also for other wildlife filmmakers!

      @arthur8448az LOL I know right?? “It’s a mystery” As soon as that was said I immediately called BS. I have no idea why they just decided to gloss over that one thing..

      NO! The research wasn't done and almost nothing was explained. We KNOW why scorpions glow under UV light but I guess that was too long to google it so they just say "idk why they is magic"... that was very disappointing (we just don't know the use of their glowing powers)
