Snails as a take home assignment


Posted on February 26, 2013 by A. T. Wyatt

McMurry biology students in Dr. Tierney Brosius’ zoology class got an interesting take home assignment yesterday.

They are all charged with up close and personal snail observations for the next 48 hours. Each student took home a snail, housed in a vial with lettuce. The snails will be observed to determine what vegetative matter they most prefer to eat and what type of activity they exhibit and when. Students are strictly charged to care for their snail, as the subject must be alive and in good condition at the conclusion of the experiment!

One observation concerns elimination of waste. Here is the question students will discuss at the conclusion of the activity: How do snails eliminate waste? How does that process of elimination affect the structure of the snail shell? Answers forthcoming after the lab is complete!
