Salamandridae is a family of salamanders consisting of true salamanders and newts. Salamandrids are distinguished from other salamanders by the lack of rib or costal grooves along the sides of their bodies and by their rough skin. Their skin is very granular because of the number of poison glands. They also lack nasolabial grooves. Most species of Salamandridae have moveable eyelids but lack lacrimal glands.

Nearly all salamandrids produce a potent toxin in their skin, with some species being deadly to many other animal species. With a few exceptions, salamandrids have patterns of bright and contrasting colours, most of these are to warn potential predators of their toxicity. They have four well-developed limbs, with four toes on the fore limbs, and (in most cases) five toes on the hind limbs. They vary from 7 to 30 cm (3 to 12 in) in length.

Many species within this family reproduce by method of internal fertilization. Additionally, there are many species-specific courtship rituals that males perform to attract mates. These courtship rituals often employ pheromones to induce mating behavior in females. Pheromones have been discovered to be the driving force behind female mating responses in Alpine newts. These pheromones can induce behavior even when male visual epigamic characters and courtship dances are absent. All species within the genus Lyciasalamandra are viviparous, meaning they give birth to live young, without a tadpole stage. There are some species within the genus Salamandra are known to be viviparous too. Some newts are neotenic, being able to reproduce before they are fully metamorphosed. The females of many species can store sperm for up to 6 months at a time.
