Toxic to Humans

Yellow-spotted millipede possesses a defense mechanism that releases hydrogen cyanide, a cyanogenetic compound, when threatened. Direct touch or ingestion by humans can lead to mild toxic effects due to hydrogen cyanide's ability to inhibit cellular respiration. Symptoms might include dizziness, headache, or nausea. No skin penetration occurs, and there are typically no severe effects from casual contact. However, high concentrations or prolonged exposure can result in more significant health complications.
