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.
Ergotism (pron. / ˈ ɜːr ɡ ə t ˌ ɪ z ə m / UR-gət-iz-əm) is the effect of long-term ergot poisoning, traditionally due to the ingestion of the alkaloids produced by the Claviceps purpurea fungus—from the Latin clava "club" or clavus "nail" and -ceps for "head", i.e. the purple club-headed fungus—that infects rye and other cereals, and more recently by the action of a number of ...
The regular form eft, now only used for newly metamorphosed specimens, survived alongside newt, especially in composition, the larva being called "water-eft" and the mature form "land-eft" well into the 18th century, but the simplex "eft" as equivalent to "water-eft" has been in use since at least the 17th century.

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 toxic skin.

Birds selectively avoid to predate all-red or erythristic color P. cinereus because they think that red color is a signal of noxiousness and toxicity. Even if people trained the birds to enhance the avoidance by increasing exposure to red efts (juvenile Notophthalmus viridescens), the frequencies of erythrism is never above 25%. [25]
[19] [20] This toxicity has been equated to being somewhere between the dusky salamander and highly unpalatable red eft. [21] The coloration and defensive posture of the mud salamander has been hypothesized to mimic that of the red eft stage of the eastern newt (Notophthalmus viridescens) which emits a powerful neurotoxin in their skin compared ...
No species of genus Amaranthus is known to be poisonous to humans, [10] but the leaves of A. retroflexus contain oxalic acid and may contain nitrates if grown in nitrate-rich soils. [11] Like many other species of Amaranthus, this plant may be harmful and even deadly when fed to cattle and pigs in large amounts over several days.
