SE micrograph of the entire telson (stinger) of the Tanzanian red bark scorpion (Babycurus jacksoni). Image includes the telson vesicle, in which the two venom-producing glands can be found. Muscles surrounding the glands will contract internally, pushing venom up through conduits to the tip of the telson (termed the aculeus). This species also features a subaculear tubercle (small protrusion above the stinger) with an unknown function. Credit: Sam Campbell/University of Queensland Scorpions wield some of the natural world's most formidable built-in weapons, from crushing pincers to venomous stingers. Scientists have long known that these structures contain trace metals that strengthen them, but only a small fraction of the roughly 3,000 scorpions have ever been examined for this trait. A new study published in the Journal of the Royal Society Interface dramatically expands that understanding.…
