Day 6 was spent on the RV Diodon, with snorkeling stops at 4 different reefs.
We docked for lunch at Indian Key, which was a settlement in the 1800s and is now a state historic site. My favorite part was the "mystery feature"...
The Century Plants were pretty cool.... they grow a huge stalk and only bloom once every ~100 years, and then die.
When we returned to the KML, the students had a quiz on algae and coral identification, so I walked around the classroom taking pictures of the specimen cases.
