While SnailBlitz 2018 is now over, read below for information on how people participated and about the 2018 photo contest.

One of NHMLA’s community science projects, SLIME (Snails and Slugs Living in Metropolitan Environments), is the first community science project that aims to catalogue the biodiversity of terrestrial gastropods (land snails and slugs) in Los Angeles County and throughout Southern California. SnailBlitz 2018 supports the SLIME project by taking advantage of our rainy weather.
