The students and I spent Monday morning learning to snorkel in a magnitude 2, fresh water spring. We learned about indigenous species found in the area. In the afternoon we visited an animal hospital that specializes in caring for a particular marine mammal. This mammal lives in both fresh and salt water. It usually feeds on vegetation found at the mouth of rivers. This is a very large marine animal. Are you getting any closer to guessing where I am? What guesses do you have and what reasons do you have those guesses?
