Triton

Presentation

The Triton is a small urodele amphibian belonging to the salamandridae family, present mainly in Europe, North Africa and Asia. It has an elongated body, smooth or grainy skin and a laterally flattened tail suitable for swimming. Unlike frogs, it retains its tail as an adult and alternates between aquatic and terrestrial life depending on the season. The male often develops an ornamental dorsal crest during the breeding season. Several species of Tritons are sometimes kept in terrarium-aquariums by NAC enthusiasts.

The Triton generally measures between 7 and 18 cm depending on the species, with often colored skin on the belly. It breathes through the skin and lungs, and can regenerate some lost limbs. Its skin secretes a protective mucus which may contain slightly toxic substances.

Characteristics

Indicative values: they vary by subspecies, sex and region.

Habitat and distribution

The Triton frequents pools, ponds, ditches and small calm streams surrounded by vegetation. Outside of the breeding season, it lives in terrestrial wetlands, under stones, dead wood or forest litter.

Behaviour

The Triton is a secretive and mainly nocturnal animal, especially active at dusk. It spends most of the year in humid terrestrial environments, then migrates to fresh water sources in spring to reproduce. It often overwinters buried in the ground or under plant debris.

Reproduction

Reproduction takes place in spring in the water, preceded by a nuptial display where the male displays his crest and his colors. Fertilization is internal but indirect, via the deposition of a spermatophore recovered by the female. It then lays its eggs one by one, often folded into the leaves of aquatic plants.

Peculiarities

The Triton is capable of regenerating a leg, part of its tail or even certain internal organs after an injury. Its skin, rich in glands, can secrete toxins that deter predators.

Threats and conservation

Degradation and drying of wetlands constitute the main threat to Tritons populations. Water pollution, the introduction of predatory fish and the fragmentation of surrounding terrestrial habitats are exacerbating its decline.
