Where does the poison from the poisonous dart come out?

The poison from a poisonous dart, such as those used by certain frogs or insects, typically comes from specialized glands in the animal's skin or body. When the dart is delivered, the poison is released from these glands, often through a sharp tip or barbed end. In the case of dart frogs, for example, their skin secretes toxins that can be absorbed or transferred to objects they come in contact with. This mechanism allows them to defend themselves against predators effectively.
