Slimy Slugs and Slippery Snails

By: Ben, Sonja, and Parker

Did you know that slugs can posses both male and female sex characteristics at the same time?

We learned this today, when we woke up at a painfully early, 4:30 A.M. to hunt for snails with Dr. Erika Iyengar. We helped her document the number of invasive slugs, compared to native banana slugs in the Friday Harbor Lab area. There were many more invasive slugs than banana slugs in the area, which is not a good sign for the native population.

After a quick breakfast back at the dorm, we went back out into the field, this time to Cattle Point. Here, we collected two species of whelks for a later experiment. Tim D. also gave us a fascinating lecture on the geology of the surrounding area.

Since we got up so early, we had a very relaxing afternoon. Some people took naps, while others watched a movie and went to get frozen yogurt.

For dinner, we had Hilary Hayford, an intertidal ecologist from the University of Washington, and Jen Olson, the stranding network coordinator of the Marine Mammal Stranding Network, as guests. Both of them gave presentations on their respective research and work.

Tomorrow, we are looking forward to observing a marine necropsy of harbor seal pups with Jen Olson.
