An orange newt may be one of several species of salamanders, including the Eastern newt, Sierra newt, rough-skinned newt or California newt. The Sierra newt can be a brownish-orange color as an adult, with a brighter underside to warn predators. The Eastern newt is an orange color during its juvenile stage only, and rough-skinned newts feature drastic color changes from the ventral and dorsal sections of the body.
The Sierra newt, or Taricha torosa sierrae, lives along the Sierra Nevada Mountains of California. These creatures eat invertebrates such as worms, insects, snails and slugs. Small amounts of toxins on the Sierra newt's skin keep predators at bay. Sierra newts may live up to 20 years in the wild.
The Eastern newt, or Notophthalmus viridescens, is also known as the red-spotted newt. This species exhibits an orange coloration between the larval stage and adulthood. Juvenile Eastern newts are bright red or orange, whereas larvae and adults are olive green. The Eastern newt is native to New Hampshire, New York and other eastern states of America.
The rough-skinned newt, or Taricha granulosa, ranges from Alaska to California. This species has a yellow or orange belly, with a darker back that is brown, black or olive green. The rough-skinned newt's skin contains toxins, especially the neurotoxin called tetrodotoxin, that sometimes irritate human skin.
