SnailBlitz 2020

From February 1 to March 31, 2020, you are invited to send NHMLAC photographs of the snails and slugs you find throughout Southern California. Help us reach our goal of 1500 observations by the end of SnailBlitz 2020.

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 2020 supports the SLIME project by taking advantage of our rainy season.

How to Participate in SnailBlitz 2020

Take a photo of any Southern California snail or slug between February 1 and March 31, 2020. Then share your photo with NHMLAC in one of four ways. Please include date and location (address or intersection) for each photo.

  • E-mail slime@nhm.org OR
  • Text 213.663.6632 OR
  • Post to Instagram, Twitter, Facebook using #SnailBlitz OR
  • Post directly to SnailBlitz 2020 project page on iNaturalist. If you don’t know what it is, you may identify it as “Common Land Snails and Slugs” or “Stylommatophora”.
