Toxicity Mechanisms
Salamanders are known to be poisonous creatures. They produce toxins in their skin secretions and accumulate toxins in their diet. The toxicity of salamanders varies by species, and the juveniles are generally more toxic than adults.
Skin Secretions
Salamanders secrete toxins through their skin, which can be poisonous when ingested. The toxins produced by salamanders include digoxin, tryptamines, tetrodotoxin, and other potent toxins. These toxins can cause a variety of symptoms such as irregular heart rhythm, dizziness, cardiac arrest, and paralysis. The skin secretions of salamanders were mostly studied in the German language, and many nuances of these studies have remained hidden from the majority of herpetologists and toxinologists [1].
Dietary Accumulation
Salamanders can accumulate toxins in their diet, which can make them poisonous. They eat insects, spiders, and other small invertebrates that can contain toxins. Some salamanders, such as the rough-skinned newt, accumulate toxins from their diet that can cause death in predators, including humans. The rough-skinned newt produces a potent neurotoxin called tetrodotoxin, which can cause paralysis and death in predators [2].
In conclusion, salamanders are poisonous creatures that produce toxins in their skin secretions and accumulate toxins in their diet. The toxicity of salamanders varies by species, and the juveniles are generally more toxic than adults. It is important to exercise caution when handling salamanders to avoid any potential toxic effects.
