SnailBlitz 2021

From February 1 to March 31, 2021, you are invited to send NHMLAC photographs of the snails and slugs you find throughout Southern California. Help us reach our goal of 1,500 observations by the end of SnailBlitz 2021.

One of NHMLAC’s community science projects, SLIME (Snails and Slugs Living in Metropolitan Environments), is the first to catalogue the biodiversity of terrestrial gastropods (land snails and slugs) in Los Angeles County and throughout Southern California. SnailBlitz 2021 supports the SLIME project by taking advantage of our rainy season.

How to Participate in SnailBlitz 2021

Take a photo of any Southern California snail or slug between February 1 and March 31, 2021. Then share your photo with NHMLAC in one of four ways. Please include date and location (address or intersection) for each photo.
