For instance "Pan troglodytes", the chimpanzee, and "Troglodytes troglodytes", the wren, are not necessarily cave-dwellers. The current primate exhibit features chimpanzees (Pan troglodytes). The ecoregion supports populations of the endangered western chimpanzee ("Pan troglodytes verus"). Chimpanzees ("Pan troglodytes") are smart, social animals. The eastern chimpanzee ("Pan troglodytes schweinfurthii") is a subspecies of the common chimpanzee. The German naturalist Johann Friedrich Blumenbach classified the common chimpanzee as "Simia troglodytes" by 1775. The common chimpanzee was named "Simia troglodytes" by Johann Friedrich Blumenbach in 1776. Or possibly the chimpanzee's scientific name should be "Homo troglodytes" instead of "Pan troglodytes". These house troglodytes, bugbears, and carrion crawlers. "Homo troglodytes" ("cave-dwelling man"). The house wren ("Troglodytes aedon") is a very small songbird of the wren family, Troglodytidae. The type species was subsequently designated as the house wren ("Troglodytes aedon"). The term "caveman" has its taxonomic equivalent in the now-obsolete "Homo troglodytes", (Linnaeus, 1758).
