DEEP: Blue-Spotted Salamander

Blue-spotted Salamander

Pure Diploid Populations

(Ambystoma laterale)

{Blue-spotted Salamander}

IDENTIFICATION: Slender, narrow head, black coloration with blue flecks, especially on belly, sides, and tail. Tail flattened laterally. Small, adults are usually under 100 mm total length.

Bogart and Klemens (1997) reported on the genetic distinctiveness of the blue spotted salamanders found in eastern Connecticut, southeastern Massachusetts, and on the tip of Long Island at Montauk. Unlike any other blue spotted salamanders in southern New England, these animals have been geographically isolated, and never have had an opportunity to hybridize with Jefferson salamanders or to come into contact with hybrid populations of blue-spotted salamanders. These animals occur in an even sex ratio of males to females. In Connecticut, these salamanders are restricted to several large swamp systems lying in the Quinebaug Valley. These populations of diploid blue-spotted salamanders, found in the towns of Plainfield and Griswold, are a "Threatened Species" in Connecticut and strictly protected on state lands. Collection is prohibited under Section 26-66-13-A of the Connecticut Code. These relictual populations of blue-spotted salamanders are unfortunately not afforded differential conservation or protection status in either New York, where they are restricted to the extreme eastern tip of the South Fork of Long Island, nor in southeastern Massachusetts where they are known from a few sites between Cape Cod and the Rhode Island line. Although these salamanders may have once occurred in northeastern Rhode Island, their habitat has been destroyed by urbanization.
