One of the most clear examples of animal suicide would most likely be the suicidal behavior of tarsiers that are kept in captivity. Tarsiers are nervous and shy by nature, and they don’t do well in captivity. Many activities associated with captivity, such as camera flashes, being touched, and being kept in an enclosure, can stress the tarsiers. This stress can lead to sore eyes, which is an indication of a poor diet, and the lighting usually used in captivity can cause long-lasting damage to the eyes. When they feel too stressed out, they start beating their heads against hard surface, which leads to death.
Aristotle described an unverified story involving one of the King of Scythia’s horses dying by suicide after having been made to unwittingly impregnate its mother in his History of Animals.
Carpenter ants and some species of termite will rupture glands and expel a sticky toxic substance thought to be an aliphatic compound in a process called autothysis. Termites will use autothysis to defend their colony, as the ruptured gland produces a sticky harmful secretion that leads to a tar baby effect in defense. When threatened by a ladybug, the pea aphid will explode itself, protecting other aphids and sometimes killing the ladybug. Another example is the Camponotus saundersi, or Malaysian worker ant, which is capable of dying by suicide by exploding.
imagine if humans could do this so people who were really depressed just one day exploded into goo.
