Aculei are specialized structures found in various animals, particularly invertebrates, that possess stinging or needle-like appendages. These structures are often sharp, pointed, and hardened, serving as a defense mechanism or for capturing prey. Common examples of animals equipped with aculei include bees, wasps, scorpions, sea urchins, and certain species of fish and plants.
Aculei play a crucial role in the survival and protection of these organisms. In bees and wasps, the aculei are modified ovipositors or stingers located at the posterior end of the abdomen, which allow them to inject venom into potential threats. Similarly, scorpions possess aculei on their tail tips, which they use to deliver potent venoms to immobilize or kill prey. Sea urchins possess sharp aculei often embedded in their calcareous endoskeleton, providing a defense against predators. Some plants also possess aculei, such as the thorns and spines on cacti, which deter animals from feeding on them.
