Banana Slug Ariolimax sp.

 
 

 At marker C19 in Big Creek canyon there is a rock face where the slugs seem to congregate (2-12-02)

 These slugs are mating near the lower edge of the rock (2-12-02)
   
   

 Many other slugs were on the rock face, mostly inactive. There are also deep cracks in the rock which could provide shelter and safety during summer dormancy. 2-12-02
