California Banana Slug

Ariolimax californicus


Species within the genus Ariolimax include: Ariolimax californicus J. G. Cooper, 1872 — California banana slug[1] Ariolimax columbianus Gould, 1851 — Pacific banana slug[1] Ariolimax dolichophallus Mead, 1943 — Slender banana slug[1][2][3] Banana slugs are often bright yellow (giving rise to the banana sobriquet) although they may also be greenish, brown, tan, or white. The species Ariolimax columbianus sometimes has black spots that are so extensive that the animal looks almost entirely black. Individual slugs will change colors with alterations in food consumption, light exposure, and moisture levels. Color may also indicate whether a slug is healthy or injured or what age it is.[4] The Pacific banana slug is the second-largest species of terrestrial slug in the world, growing up to 25 centimetres (9.8 in) long,[5] and weights of 115 grams (4.1 ounces).[6] (The largest slug species is Limax cinereoniger of Europe, which can reach 30 centimetres (12 in) in length.) Banana slugs have an average lifespan of 1-7 years. [7]
