The Black Salamander has toes with rounded tips. Compare with the Aneides vagrans, the Wandering Salamander, and Aneides ferreus, the Clouded Salamander, which have toes with squared-off tips.

Short Video
A Black salamander is discovered under a rock on a sunny late November afternoon in Mendocino County. Several adults and a juvenile move slowly and with amazing bursts of speed.

Description
Size
Adults measure 2 - 3 3/4 inches long (5.1 - 9.5 cm) from snout to vent, and up to 5.5 inches (14 cm) total length.
Appearance
A medium-sized plethodontid salamander with two nasolabial grooves and 14 - 16 well-defined costal grooves. Dorsal coloring varies depending on the locality - it can be solid black, black with fine white specks, black with large white spots, black with pale yellow spots, black frosted with green or gray, or black with many small white spots. The venter is greyish black. Males have a broader head than females.
Young are black with a brassy or greenish coloration and yellow at the base of the limbs.
Behavior and Natural History
Lives in moist places on land. Adapted for climbing with long toes and rounded prehensile tail, but mostly terrestrial. Breathes through thin moist skin instead of lungs. Adults forage for small invertebrates on the ground at night during wet weather. May be active along streams all year at the southern part of its range, but most stay underground during dry periods. Adults appear to be agressively territorial. Black Salamanders have lived as long as 20 years in captivity.

When threatened, juveniles typically remain still while adults attempt to flee. Other defense tactics include defensive posturing - raising the body, lowering the head, and waving the tail, jumping, releasing noxious sticky skin secretions, and biting.
Diet
Diet consists of a variety of small invertebrates, including millipedes, ants and termites. As salamanders grow larger, they eat fewer, but larger prey items.
Reproduction and Young
Reproduction is terrestrial. Courtship and breeding behavior is not well known. Breeding males have a well-developed mental gland. Females probably lay from 8 - 25 eggs in moist cavities belowthe ground in July and August. Eggs are attached by peduncles. Females stay with the eggs until they hatch. Young develop completely in the egg and hatch fully formed.
Range
Endemic to California and a small area in extreme southwest Oregon. Occurs from Sonoma county north along the coast and coast ranges to southwest Oregon in Jackson and Josephine Counties, and east to near Mt. Shasta.
Habitat
Occurs in mixed deciduous woodland, lowland coniferous forests, coastal grasslands. Found under rocks near streams, in talus, under damp logs, and other objects.
Most common at low elevations, but found from near sea level to over 5,500 ft. (1,700 meters.)
Taxonomic Notes
Aneides flavipunctatus occurs in three geographically isolated regions. The southern population in the Santa Cruz region is currently recognized as the subspecies A. f. niger by some researchers, or as the species A. niger by others. The group south of Mt. Shasta is also isolated from populations to the west.


In a study published in 2007 1, Rissler and Apodaca determined that even though there is little morphological divergence across the species, the use of mtDNA analyses and ecological modeling indicates that there are four separate main lineages of A. flavipunctatus which eventually should be given full species status: A Southern Disjunct lineage on the San Francisco Peninsula and in the Santa Cruz Mountains; a Shasta lineage in the Mount Shasta region; a Central lineage on the north coast and north coast ranges north of San Francisco Bay; and a Northwest lineage in the northwest corner of the state including Humboldt, Del Norte, and Siskiyou Counties. There is another population within the Central Lineage which is also distinct, but they do not discuss this in detail. They recommended that the Shasta and Southern lineages be elevated to species status, but that more work is needed to determine the southern extent of the Northwest lineage. Once that has been determined, they recommend that the Northwest lineage also be elevated to species status. The new names will most likely be

Aneides flavipunctatus
for the Central Lineage,

Aneides niger
, for the Southern Disjunct lineage, and

Aneides iëcanus
, for the Shasta lineage.

A new name or names will be given to the other lineage(s).

Conservation Issues  (Conservation Status)
Disappeared from many areas of their range. Much prime habitat has been lost when it has been converted to agricultural use, especially vineyards, and probably through logging of forests.

Conservation Status

The following status listings come from the Special Animals List which is published several times each year by the California Department of Fish and Game.

This salamander is not included on the Special Animals List, meaning there are no significant conservation concerns for it in California according to the California Department of Fish and Game.
