Nonindigenous Occurrences: Two C. pyrrhogaster were collected from Ward's Pond, Plymouth County, Massachusetts in 1932 (Cardoza et al., 1993). An additional escaped pet was collected in 1979 from Stoneham, Middlesex County, Massachusetts (Cardoza et al.,1993). In 1964, C. pyrrhogaster were released into Hialeah (Red Road) Canal, Miami-Dade County, Florida (King and Krakauer, 1966).
Means of Introduction: The Massachusetts introductions were released or escaped pets and the Florida introduction was intentionally released by an animal dealer (King and Krakauer, 1966; Cardoza et al., 1993).
Status: The introductions in Florida and Massachusetts did not result in an established populations (Cardoza et al., 1993)
Impact of Introduction: Since the salamanders did not become established, no impacts have been documented.
Remarks: In Japan, C. pyrrhogaster are found in ponds, rice fields, swamps and streams. They eat aquatic insects and tadpoles. The more terrestrial juveniles can be found under logs, rocks and leaf piles (Okada, 2000).
