The juvenile is dark overall, clouded with greyish color and fine yellow speckling on the back. The male of this species can be distinguished by its broad triangular head, with the front teeth of the jaw extending beyond the bottom lip. A large adult can inflict a painful bite.
This species is an excellent climber and difficult to capture. It is nocturnal, spending daylight hours and dry periods in the cavities of oak trees, often with many other individuals of its species. Having their primary habitat being in the trees, arboreal... Wikipedia →

Rare
Under 5% of wildlife watchers report an Arboreal Salamander sighting in San Diego on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 6th most-seen of the 6 amphibians we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report an Arboreal Salamander in San Diego on a given day, so our monthly data shows no clear season.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Arboreal Salamander sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is seen both by day and at night.
2nd of 2
Of the 2 cities where we can rate Arboreal Salamander sightings, San Diego ranks 2nd at under 5%. The best odds are in San Francisco (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the Arboreal Salamander is recorded against all the amphibians logged in San Diego (6 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
