Back Again! After nearly &ldquo;decapitating&rdquo; this russula the slug came back to taste the margins of the cap. I interrupted it to take this photo,<br />

  1. Your honor, I present you evidence A. Posted 6 years ago
    1. Yes, the thing that surprised me the most was that we noticed the top of the mushroom missing on the start of our walk and there was no slug. About an hour later when we returned the slug had reappeared and eaten that much of the edge. I just didn’t realize how much that one slug could consume in so little time. The cap of the mushroom WAS 4cm in diameter. Posted 6 years ago
      1. WOW, hungry slug!! I too have noticed mushrooms at the start of a hike partly eaten by a slug, only to find it mostly eaten on the return a few hours later.

        Have you noticed that the slugs really seem to love Russulas? I rarely find an intact Russula.

        1. Have to say that I agree with you. They must be able to sense where the Russulas are. Posted 6 years ago

Ariolimax columbianus is the second largest land slug in the world. Adults range from 15-20cm in length. Some have been recorded at 25.4 cm! Augustus A. Gould first gave these soft bodied invertebrates a scientific name in 1851. Some of the first studies were conducted along the Columbia River; hence the species name A. columbianus (Harper 1988). Gastropoda describes the banana slugs stomach-foot or muscular-foot, which allows them to slowly crawl on a series of muscular waves (Denny 1980). Pulmonata.. more
