Description

The black-spotted newt grow to 2.9-4.3 in (7.1–11 cm) long, and is typically an olive green in color, with numerous black spots. The underside is often yellow in color, which can sometimes extend up to the sides. They have smooth skin, and a paddle-shaped, vertically flattened tail. They live in quiet stretches of streams and permanent and temporary ponds and ditches.

Behavior

Black-spotted newts prefer shallow-water habitats, heavy with vegetation. During the dry season, they are believed to burrow underground or remain under debris. They are carnivorous, consuming a wide variety of prey, including insects, aquatic invertebrates, leeches, and other amphibians. Their toxic skin secretions are used to deter predators. Breeding occurs year-round. The life history of this species is not well known and the presence of an eft stage has yet to be determined.

Range

Notophthalmus meridionalis can be found in the states of Tamaulipas, Veracruz, and San Luis Potosí in Mexico, barely extending into northeastern Hidalgo and Puebla. It is also found in southern Texas along the Gulf of Mexico.

Conservation

The black-spotted newt is listed as a threatened species in Texas[2] and as an Endangered species by the IUCN

gollark: One problem with solar/wind is that (like most things) they degrade over time (lithium ion batteries, which you could end up needing many of, especially fast), and would be in remote locations in huge quantities...
gollark: Nuclear also doesn't take up much land, and could be way more efficient than it already is if it was actually deployed at scale and new technologies got used.
gollark: The waste is basically a non problem compared to carbon dioxide and they run constantly.
gollark: Nuclear is far superior to foolish wind/solar.
gollark: Though we could compromise on $25$.
