Aculeate

Referring to an organism, particularly insects, possessing or characterized by sharp, needle-like structures, such as spines, prickles, or stingers. This term often describes the ability to inflict a sting or puncture, typically used in defense or for predation. The structures themselves, the aculei, may contain venom or other substances that cause pain or harm. The term implies a potential for a painful or hazardous interaction with other organisms and reflects an evolutionary adaptation for survival.
