Fire Salamander reproduces by
Answers
Fire salamanders are possibly the easiest of all salamanders to breed in captivity. Unlike many of the lunged salamanders, Salamandra species mate on land. Males produce a cone of jelly tipped by a packet of sperm. ... The male leads the female over the spermatophore, and she stands over it and takes it up into her cloaca.

S. salamandraIt is black with yellow spots or stripes to a varying degree; some specimens can be nearly completely black while on others the yellow is dominant. Shades of red and orange may sometimes appear, either replacing or mixing with the yellow according to subspecies.[2] This bright coloration is highly conspicuous and acts to deter predators by honest signalling of its toxicity (aposematism)[3] Fire salamanders can have a very long lifespan; one specimen lived for more than 50 years in Museum Koenig, a German natural history museum.Males and females look very similar except during the breeding season when the most conspicuous difference is a swollen gland around the male's vent. This gland produces the spermatophore, which carries a sperm packet at its tip. The courtship happens on land. After the male becomes aware of a potential mate, he confronts her and blocks her path. The male rubs her with his chin to express his interest in mating, then crawls beneath her and grasps her front limbs with his own in amplexus. He deposits a spermatophore on the ground, then attempts to lower the female's cloaca into contact with it. If successful, the female draws the sperm packet in and her eggs are fertilized internally. The eggs develop internally and the female deposits the larvae into a body of water just as they hatch. In some subspecies, the larvae continue to develop within the female until she gives birth to fully formed metamorphs. Breeding has not been observed in neotenic fire salamanders.
In captivity, females may retain sperm long-term and use the stored sperm later to produce another clutch. This behavior has not been observed in the wild, likely due to the ability to obtain fresh sperm and the degradation of stored sperm.[7]
