The skin of some species contains the powerful poison tetrodotoxin; these salamanders tend to be slow-moving and have bright warning coloration to advertise their toxicity. Salamanders typically lay eggs in water and have aquatic larvae, but great variation occurs in their lifecycles. Some species in harsh environments reproduce while still in ...
Most toxic amphibians are poisonous to touch or eat. These amphibians usually sequester toxins from animals and plants on which they feed, commonly from poisonous insects or poisonous plants. Except certain salamandrid salamanders that can extrude sharp venom-tipped ribs, [1] [2] and two species of frogs with venom-tipped bone spurs on their ...
Spotted salamanders do produce poisonous skin secretions, which allow them to taste bad to predators. For a human, these skin secretions are more irritating and would not kill an adult or even a ...
Unlike other salamanders, whose larvae are developed in water, the alpine salamander and its subspecies are a fully terrestrial species in life and gestation. [8] They give birth to live young. [9] Alpine salamanders produce toxic compounds from their skin. [8] These compounds may protect them from both predator and microbial threats. [10] [11 ...

Their skin is very granular because of the number of poison glands. They also lack nasolabial grooves.

Their habitats are damp woodlands, forests, and places with soft and wet soil. Seasonally flooded areas are essential for breeding, but the adult salamanders are terrestrial. Like many salamanders, marbled salamanders have poison glands to deter predators. [5] The marbled salamander is the state salamander of North Carolina. [6]
