The red eft (juvenile) stage is a bright orangish-red, with darker red spots outlined in black. An eastern newt can have as many as 21 of these spots. The pattern of these spots differs among the subspecies. An eastern newt's time to get from larva to eft is about three months.
A newt is a salamander in the subfamily Pleurodelinae. The terrestrial juvenile phase is called an eft. Unlike other members of the family Salamandridae, newts are semiaquatic, alternating between aquatic and terrestrial habitats. Not all aquatic salamanders are considered newts, however.
The red salamander (Pseudotriton ruber) is a species of salamander in the family (Plethodontidae) (lungless salamanders) endemic to the eastern United States. Its skin is orange/red with random black spots. Its habitats are temperate forests, small creeks, ponds, forests, temperate shrubland, rivers, intermittent rivers, freshwater, trees springs.
The red-bellied newt is also similar but has dark irises vs. yellow in the California newt, more red coloration underneath, and a dark band across the vent that is lacking in the California newt. [7] [citation needed] Newts are amphibians. They are related to salamanders (in a subfamily called Pleurodelinae). They live in North America, Europe ...
A terrestrial subadult Eastern newt or red eft, Notophthalmus viridescens. Salamanders of the family Salamandridae with aquatic adult stages are called newts. Some newts, including the Eastern newt, have a juvenile terrestrial stage called the eft. The red eft has aposematic coloring to warn predators of its highly toxic skin.
The red salamander (Pseudotriton ruber) is a palatable species with a similar coloring to the red eft. Predators that previously fed on it have been shown to avoid it after encountering red efts, an example of Batesian mimicry. [53] Other species exhibit similar mimicry.
Eurycea longicauda, commonly known as the long-tailed salamander [5] or longtail salamander, [6] is a species of lungless salamander native to the Appalachian Region of the eastern United States. It is a " cave salamander " that frequents twilight zones of caves and also inhabits springs and surrounding forest.
In this way, newts are able to differentiate whether a snake is resistant or sensitive to the toxin in order to avoid being preyed upon. However, newts do not avoid the corpses of a recently digested newt that has been left to decompose. This behavior is unlike salamanders that have been documented in avoiding other injured salamanders. [14]
