Snail Lab


In this lab we observed and read about snails. We learned that snails are really slow, moving at only 3 mph.We also saw it eat. The snail grinds up its food with small sharp rows of teeth called radula. One thing we were told not to do was to pick up the snail by its shell. A snail's shell is pretty fragile, sometimes as thin as paper. In our groups we swabbed some vinegar in front of the snail, instead of running into it turned away. Snails have a keen sense of smell; they know when to avoid acidic substances such as vinegar. However, we have yet to find out what gender our snail is.
