Ambystoma laterale (Ambystomatidae), the Blue-spotted Salamander, is a species found in North America from southeastern Quebec to Lake Winnipeg, south through Great Lakes region and New England to northern Indiana and New Jersey.
It is known that Ambystoma laterale hybridizes with A. jeffersonianum over a large area south of this range. So, being found in Allen County and in the hybrid zone the Blue-spotted shown in the photo would be more than likely of the Jefferson’s / Blue-spotted complex salamander or Hybrid Blue-spotted. Also known as a Unisexual Hybrid Salamander.
Hybrid populations result from the breeding of Blue-spotted Salamanders with other members of the Ambystoma genus. Most hybrids are triploid females. Normal salamanders are diploid, having two sets of chromosomes in their body cells; triploid salamanders have an extra set.
