👉 Ant fluids, also known as formic acid or hydroformic acid, are chemical substances produced by certain species of ants as a defense mechanism. These fluids are highly toxic and irritating to many organisms, including insects and vertebrates, making them an effective deterrent against predators. When an ant encounters a threat, it can release these fluids from specialized glands located near its mouthparts or abdomen, spraying them in a targeted manner to confuse or repel the attacker. The acidic nature of these fluids can also damage the protective cuticle of predators, further enhancing the ant's defensive capabilities. This chemical defense system is a crucial adaptation that helps ants survive in various ecosystems, ensuring their continued presence and ecological role.
