Toxungen

Experimentally induced toxungen spraying by the scorpion Parabuthus transvaalicus.

Toxungen comprises a secretion or other body fluid of one or more biological toxins that is transferred by one animal to the external surface of another animal via a physical delivery mechanism.[1] Toxungens can be delivered through spitting, spraying, or smearing. As one of three categories of biological toxins, toxungens can be distinguished from poisons, which are passively transferred via ingestion, inhalation, or absorption across the skin, and venoms, which are delivered through a wound generated by a bite, sting, or other such action.[2] Toxungen use offers the evolutionary advantage of delivering toxins into the target's tissues without the need for physical contact.[3]
