|
| 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 salamander with two nasolabial grooves and 14 - 16 well-defined costal grooves. |
| Color and Pattern |
| 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. |
| Male/Female Differences |
| Males have a broader head than females. |
| Young |
Young are black with a brassy or greenish coloration and yellow at the base of the limbs.
|
| Life History and Behavior |
A member of family Plethodontidae, the Plethodontid or Lungless Salamanders.
Plethodontid salamanders do not breathe through lungs. They conduct respiration through their skin and the tissues lining their mouth. This requires them to live in damp environments on land and to move about on the ground only during times of high humidity. (Plethodontid salamanders native to California do not inhabit streams or bodies of water but they are capable of surviving for a short time if they fall into water.)
Plethodontid salamanders are also distinguished by their naso-labial grooves, which are vertical slits between the nostrils and upper lip that are lined with glands associated with chemoreception.
All Plethodontid Salamanders native to California lay eggs in moist places on land.
The young develop in the egg and hatch directly into a tiny terrestrial salamander with the same body form as an adult.
(They do not hatch in the water and begin their lives as tiny swimming larvae breathing through gills like some other types of salamanders.)
|
| Activity |
Adapted for climbing with long toes and rounded prehensile tail, but mostly terrestrial.
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. |
Territoriality
|
| Adults appear to be agressively territorial. |
| Longevity |
| Black Salamanders have lived as long as 20 years in captivity. |
| Defense |
| 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 and Feeding |
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 |
Reproduction is terrestrial.
Courtship and breeding behavior is not well known.
Breeding males have a well-developed mental gland.
|
| Eggs |
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 |
Young develop completely in the egg and hatch fully formed.
|
| Comparison With Other Black Salamanders |
"This species is distinguished from other members of the Aneides flavipunctatus as follows:
from A. klamathensis in having variable coloration but generally lacking the frosted dorsal coloration, especially in the southern parts of its range, and only a few populations have 17 trunk vertebrae;
from A. iecanus in it more variable coloration and habitat preferences;
from A. niger in its more variable coloration but rarely with so few iridophores."
(Reilly and Wake 2019)
|
| Habitat |
Occurs in mixed deciduous woodland, lowland coniferous forests, coastal grasslands.
Found under rocks near streams, in talus, under damp logs, and other objects.
|
| Geographical Range |
Occurs near the coast north of the San Francisco Bay Area from Sonoma county north along the coast and coast ranges to Humboldt and Trinity counties and east into Lake, Napa, Yolo and Colusa, counties and possibly north into Glen and Tehama counties.
"Geographical Distribution: From northern Sonoma and Napa counties north into southern Humboldt County near Cape Mendocino and Larabee Creek, east to the interior edge of the coast ranges. As mentioned above, populations along the inner margins of the Coast Ranges in western Tehama and Glenn Counties ... are of unknown status, and further surveys including morphological and genetic analyses of these populations are needed to confirm their taxonomic designation."
(Reilly and Wake 2019)

| Taxonomic Notes |
Aneides flavipunctatus was split into four species in August, 2019. The subspecies Aneides flavipunctatus flavipunctatus was elevated in rank to a full species.
In a 2019 paper Reilly & Wake confirmed that Aneides flavipunctatus consists of four species:
Klamath Black Salamander - Aneides klamathensis Stebbins, 1951 & Dubois and Raffaelli, 2009
Speckled Black Salamander - Aneides flavipunctatus (Strauch 1870)
Shasta Black Salamander - Aneides iecanus (Cope 1883)
Santa Cruz Black Salamander - Aneides niger Myers & Maslin 1948
(Reilly and Wake 2019)
In a 2014 paper, Reilly and Wake continue to show four species-level units of A. flavipunctatus, including the isolated population south of the San Francisco Bay, but they do not describe any new species.
(Reilly and Wake 2014)
In a study published in 2007, 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.

| 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.
The population in Shasta County should be given special conservation consideration, as it is the most distinct population genetically, and may represent a species distinct from Aneides flavipunctatus.

The following conservation status listings for this animal are taken from the April 2024 State of California Special Animals List and the April 2024 Federally Listed Endangered and Threatened Animals of California list (unless indicated otherwise below.) Both lists are produced by multiple agencies every year, and sometimes more than once per year, so the conservation status listing information found below might not be from the most recent lists. To make sure you are seeing the most recent listings, go to this California Department of Fish and Wildlife web page where you can search for and download both lists:
https://www.wildlife.ca.gov/Data/CNDDB/Plants-and-Animals.
A detailed explanation of the meaning of the status listing symbols can be found at the beginning of the two lists. For quick reference, I have included them on my Special Status Information page.
If no status is listed here, the animal is not included on either list. This most likely indicates that there are no serious conservation concerns for the animal. To find out more about an animal's status you can also go to the NatureServe and IUCN websites to check their rankings.
Check the current California Department of Fish and Wildlife sport fishing regulations to find out if this animal can be legally pursued and handled or collected with possession of a current fishing license. You can also look at the summary of the sport fishing regulations as they apply only to reptiles and amphibians that has been made for this website.
This species 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 Wildlife.
