It was total slugville underneath the redwoods and madrones at Mt. Madonna in the gentle rain. I easily lost count of how many native banana slugs we spotted during our hikes. True to my blog rules, all of these unedited pictures were taken on 12/21/10. They're fairly camera shy and quickly retracted their optical and sensory tentacles as we walked up to them. It took more patience than I generally have while waiting for the tentacles to reappear for the first photo above. Many of the banana slugs were longer than the span of my hand, from thumb to pinky, i.e., > 7". Most appeared to have egg masses sticking to their tail ends. Or it could have been the
mucous/slime plug I've read about?
I was hoping to be able to ID the banana slug to species, but my numerous internet searches didn't offer any information on how to distinguish between
Ariolimax columbianus (Pacific banana slug),
A. dolichophallus (slender banana slug), and
A. californicus (California banana slug). Color does not seem to be an identifying trait as they can be white, black, brown, or varying shades of yellow, all with or without spots. Not even my
Field Guide to the Slug had any identifying information within the
Ariolimax genus. However, I did find more sites about
slug sex than I ever wanted to know.
For more information, click on any of the embedded links above, or check out a favorite local blogger's very nice summary of banana slugs at
Curbstone Valley Farm. If anyone has better information, I'd love to hear from you.
