The black-spotted newt (Notophthalmus meridionalis), also called Texas newt, is an aquatic newt species of the family Salamandridae. The genus Notophthalmus consists of three Newt species, striped newt, eastern newt, and black-spotted newt.
The genus name consists of two Greek elements, noton means 'back,' and ophthalmus means 'eye.' They belong to the subfamily Pluerodenilae and newts in this subfamily are semiaquatic.
The old English name for newts was efte and efeta.
As the name suggests, the black-spotted newt has several black spots on the olive green or silvery-gray body. The U.S Fish and wildlife service (FWS) studied 221 historical populations in the mid-'80s and discovered that only five remained in their native, three in Mexico and two in Texas.
The research data on the black-spotted newt suggests that these species are threatened by massive habitat loss and are decreasing in population density due to which are likely to go extinct. They are currently Endangered species.

How do they reproduce?
The breeding season of black-spotted newts is throughout the year. Breeding takes place in damp places like ponds. The breeding behavior is variable and complex.
The males have pheromone-producing organs either on the head or open into the cloaca. These pheromones alter the female's hormonal state which makes her receptive. The makes develop powerful big hind limbs with horny patches on their inner surface and tail fin.
To capture the female the males use their limbs in a rapid movement. The male first deposits his sperm close to the female and pushes her over the sperm. The female then takes up the sperm into her cloaca.
The female stores the sperm in the spermathecae organ. Some of these species especially the eastern newts are highly oriented and return to their breeding habitat. Also, these species lack an eft stage commonly seen in the eastern newt species.
What is their conservation status?
The conservation status of the black-spotted newt population is Endangered. Much of the range of their habitats are lost due to clearing.
The texas parks and wildlife department has taken up conservation actions for the recovery of the habitat and population of these species. The Texas parks and wildlife department is conducting surveys on the habitats used by these species in their life history and are also calculating diversity metric for every site.
