Your family decides to spend a long weekend at Yellowstone, hiking and camping. Thinking what fun you will have seeking out various species of protists and alga, you pack your microscope. Unfortunately, in the middle of the second day of hiking, you discover an amazing patch of lichen you are certain must house Trebouxia (a protist symbiont). You want to take a sample back to camp and while you are gathering, you become separated from the group. Two days later, out of water, you resort to drinking from streams. The next day you are rescued (your lichen samples are still intact!) and they rush you back to the local wilderness station for a quick examination. In good humor from your rescue, but not so much from the activity in your colon, you inform them, “I’m fine, really. But
something is Excavata in my gastrointestinal tract!” You are the only one that laughs. What have you got in your gut? a. diatoms, and their glassy cell walls are causing you no end of discomfort b. Euglena, which use their flagella to move freely about the gut c. Giardia lamblia, a waterborne protist that causes severe diarrhea when ingested d. Dinoflagellates because the water in Yellowstone is brackish from the intertidal zone
