After lunch we traveled by boat to Pigeon Cay for a geology walk. The karst at Pigeon Cay makes for a very interesting rocky coast. There are tons of pockets for tide pools to form, and we saw fuzzy chitons, mussels and whilks galore. We also saw a whip-tailed stingray off the shore. The island has some interesting features, such as mounds of shells from hurricanes and fracture lines from hydrostatic pressure.

While still at Pigeon Cay, we did the gonio lab. We cracked open goniopora algae samples carefully to examine the small invertebrates using them as a home. I was working with Tom and Robin We saw brittle stars, small crabs, snapping shrimp, and a tiny common atlantic octopus! After the lab when we were moving back towards the boat we saw a cushion star, which was cool. I like looking at their tiny tube feet.

After Pigeon Cay, we went to snorkel at 2 locations. The first was Blue Hole Cay, an oceanic blue hole with serious Katy Perry vibes ("cause you're hot then you're cold"). The cold water seeping from the blue hole mixing with the hot water where the shallow grasses were was pretty jarring. But we saw an Atlantic stingray, and I saw a new kind of sea cucumber I hadn't seen before that was orangey. Then, best of all, Jordan, Julie, and Alejandra pointed out to me a massive spotted sea hare - my first nudibranch! I was very excited. Then after Blue Hole Cay we went to Dave's Patch Reef, where Zach pointed out a Flamingo's Tongue to me, and everybody helped me see a trumpetfish.
