Definition
Aculea (plural) refers to the small prickles or spines found on plants and animals. Think of them as tiny natural defenses. 🌵 Unlike thorns, which are modified branches, or spines, which are modified leaves, aculea are outgrowths of the epidermis or outer layer of tissue. They're often found on roses and other prickly plants. So, aculea are nature's tiny armor, protecting plants and animals from being eaten or touched.
