Pacific sideband snail, Monadenia fidelis
The following pictures are of a Pacific Sided snail that I found while looking at ferns along a trail.  It sat there almost still on a slab of slate, in a small sunny spot beneath ferns and cedars.  It is actually the first I've ever seen in the wild.  It is an elegant snail, with a smooth side banded shell, a lovely mosaic dark green on slighter green background, elegant as can be. One or two of the photos show the eyes.

I brought this elegant sidebanded snail into my office to highlight its anatomy and slime (some people think slime is gueuy, when in fact it's like butter or mayonaise on bread.  Snails don't eat the slime but they do use it like we use hiking trails, ski trails or slides to jump into a pool on a summer's day, even suntan lotion to protect our skins. We cover outselves with slime then, don't we?!

Now you may ask, "Why would I let that thing on my desktop and computer?" Well, my computer was dusty and needed cleaning anyway and, more importantly, what a better place to see the glow of trails!

Want to see the eyes up close?

Note the sizes of those eye stalks with the centimeter ruler behind them. While they seem tiny, they are actually rather large!

These YouTube addresses have short shots of pacific sideband snails in motion near a ruler. This will give you an impression of both size and speed.  Not you can see just the small dots (top stalked eyes) barely.

Want Moree?  There are many YouTube videos of this and other snails. However, because searching on the internet generally is fine, occassionally there are reasons to have a teacher, parent, or someone familiar to you to check out those  videos first to make sure no unwanted video appears.
I will be taking some field shots to illustrate more on how the snails behave. This will go on gradually. Feel free to send your photos in with your name/s, dates and locations on them. I can pose those still-shots here on this website, with all rights to show these on the site released.
