Common Name and Body Shape

This species, commonly called the Oregon slender salamander, has a long, thin body.

Size Measurements

Adults reach a maximum snout–vent length of 61 mm (2.4 in), and a maximum total length of 120 mm (4.7 in); most individual salamanders are smaller than these maximum measurements.

Hind Foot Toe Count

They have four toes on each hind foot.

Reproductive Clutch Details

Clutch size ranges from 3 to 11 eggs, and each egg measures 4 mm in diameter.

Endemic Range

Natural Habitat Types and Elevation

Its natural habitats are moist temperate forests in Oregon, including Douglas fir, maple, and red cedar woodlands, up to an elevation of 910 metres (3,000 ft).

Old Growth Forest Association

This species is typically associated with old growth, late-successional Douglas fir forest.

Earlier Succession Habitat Occupancy

However, it has also been found in earlier succession forests that host large logs and abundant downed woody debris.

Microhabitat Preferences

It is most often found within large diameter decayed logs, and prefers habitats with a closed canopy.

Suburban Occurrence

The Oregon slender salamander has also been recorded in a suburban landscape.
