Did You Know?
Marbled Salamanders are unique among Virginia’s mole salamanders in that they breed in the fall and guard their terrestrial eggs.
Role in the Web of Life
Breeding often occurs in late-September or October. Males enter the dried pools first and after courting females, deposit their spermatophores. Females then pick up the sperm packets in their cloacae for internal fertilization. Winter rains stimulate hatching. Larvae eat zooplankton, small invertebrates, and other salamander larvae. Adults eat mostly invertebrates such as worms, and insects.
Species appears to be secure in Virginia.
