The red eft (juvenile) stage is a bright orangish-red in color, 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 unknown.
The Eastern (red-spotted) newt is a widespread, native salamander of New York State and eastern North America that can live for 12-15 years! Larvae live in water and use gills to breathe. However, juveniles (also known as “efts”), become land dwellers and develop lungs to breathe air.
The red-spotted newt is more or less ubiquitous throughout eastern North America. The usual life cycle of this species includes three distinct post-hatching stages: (1) aquatic larva, (2) terrestrial (juvenile) eft, and (3) aquatic adult.
Adult newts are usually 3 to 5 inches in length. The juvenile, or eft, stage of the red-spotted newt is bright orange in color with small black dots scattered on the back and a row of larger, black-bordered orange spots on each side of the back.

The red-spotted newt is the only species of newt in central and southern Ontario. The central newt, a subspecies found in Ontario west of Lake Superior, has a darker back and fewer spots. Habitat. Adult newts are generally found in slow-moving water in a variety of ponds and lakes, and along quiet stretches of streams and swamps.
Alone among salamanders found at the station, the eastern red-spotted newt is a member of Salamandridae, the family that comprises all “true salamanders” and newts.It is one of only 7 species of newt in North America, out of only 87 species worldwide.
