California Banana Slugs

The genus Ariolimax is currently broken into 5 taxa in 2 subgenera based on penis morphology:

  1. A. columbianus - ranges from central California to southeast Alaska (spotted?)
    There are 2 clades within A. columbianus, for which scientists propose species rank:
    A. columbianus - ranging from northwest California to southeast Alaska
    A. buttoni - in north-central California

  2. A. californicus - found mainly in San Mateo county
  3. A. dolichophallus - found mainly in Santa Cruz county
  4. A. brachyphallus has a disjunct distribution on the northern tip of the San Francisco Peninsula, the Monterey Peninsula in Monterey County, and Cambria in San Luis Obispo County.

  5. A. stramineus - found on the coast of south-central California
    A fourth distinct clade is an undescribed species on Mount Palomar, San Diego County, California.

On December 29, 2018 I obscured my 104 observations of Banana Slugs because they were all identified only to the genus level and banana slug species are endangered.

On March 11, 2020, I've unobscured my 107 banana slug observations because I was told that scientists want them unobscured to facilitate their study. See this discussion: https://www.inaturalist.org/flags/461110

On February 22, 2024, my family and I hiked the Dool Trail at Big Basin Redwoods State Park and found 54 banana slugs along a 2.5 mile stretch of that trail. So cool! It's been a long time since I've seen so many banana slugs.
