Researchers want your help in finding some of L.A.'s more elusive residents — snails.

Why it matters

It turns out that terrestrial gastropods — also known as snails and slugs — are pretty good indicators of how of well nature is surviving in our urban landscape.

As Sam Tayag of the L.A. County Natural History Museum told us: "Snails and slugs evolve so quickly and respond so quickly as well to habitat changes, they give us a lot of clues early on."

Why now

It's Snail Blitz 2023! The two-month event enlists citizen scientists to help researchers document snails and slugs in Southern California. It started Feb. 1 and lasts through March.

The push is part of the year-round SLIME (Snails and slugs Living in Metropolitan Environments) community project. (And yes, they do have a way with acronyms and puns.)

How to participate

When you spot a snail or slug, snap a photo and note the date time and place. Upload your photos through iNaturalist, email them to the museum ( or post to Instagram or Twitter with the hashtag #SnailBlitz2023.

Where to look

Tayag recommends looking in the evening under leaf piles, fallen branches or potted plants.

"Lift up those pots and you'll probably find a couple slimy buddies under there," Tayag said.
