Stink gland
A stink gland is generally a gland that emits an unpleasant smelling substance. The secretions very often serve as a means of defense against attackers and, in addition to the malodorous substances, can often also contain defense secretions , such as acids or poisons. In addition, they often serve for intra-species communication.
Stink glands are not restricted to certain animal groups, but they are mainly found in insects ( bed bugs , click beetles ) or mammals . In the latter, they are derived from sweat or scent glands . Various species of martens such as polecats and zorillas and especially the skunks are known for their stink glands .
