red eft
Definition
- Noun:
- A terrestrial life stage of a common North American newt: A "red eft" is the juvenile, land-dwelling phase of the Eastern newt (Notophthalmus viridescens), characterized by its bright reddish-orange color with distinctive red spots outlined in black.
Usage
- The term "red eft" is used specifically in biology and herpetology to describe this particular life stage of the newt. It is a common sight in forests of eastern North America.
Examples
