[15] However, the toxins are only dangerous if ingested or otherwise enter the body; for example, through a wound.
Many salamanders do not use vocalisations, [70] and in most species the sexes look alike, so they use olfactory and tactile cues to identify potential mates, and sexual selection occurs. Pheromones play an important part in the process and may be produced by the abdominal gland in males and by the cloacal glands and skin in both sexes.
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 skulls, amphibians are not known to actively inject ...

Male marbled salamanders have also been shown to have a higher survivorship than females.
