Slimy Banana slugs need little introduction. Honored as the official mascot of the University of California, Santa Cruz, they can often be seen on huge roadside hoardings and printed on t-shirts. The second largest species of slug in the world, Banana slugs live on the damp forest floors of the Western United States.
Usually bright yellow in color, the Banana slug is a shell-less mollusk which can grow up to 15-25 cm (5.9-9.8 in) in length. Banana slugs eat many different foods such as plants, rotting fruits, animal waste, and surprisingly other banana slugs too! But the most bizarre fact concerns their strange mating habit, where one slug chews the penis off its partner after finishing sex. Chomp… Chomp! Interesting but disgusting.
