Red-necked keelback snakes possess a potent toxin derived from the toads they consume, which can cause severe harm to predators like mongooses. The snakes store these toxins in specialized nuchal glands.
Something so tiny and trivial if ignored could have led to my thumb or hand being removed, or sepsis could have set in.
