Day 3, Tuesday May 20, 2015

The food at Casa Neptune (aka TREC) is wonderful.  Today we feasted on banana pancakes, fresh pineapple, watermelon, and homemade cinnamon bread for breakfast, chicken salad sandwiches, all-you-can-eat peanut butter and jelly sandwiches, and the best-ever black bean dip for lunch, and spaghetti with meatballs, salad, hot rolls, and brownies for dinner.  Hours of snorkeling do wonders for the appetite.  Today our captain and guide were once again Chicho and Maureen, but our boat, the Valeria (aka Suya I) was a larger version of yesterday’s. We were delighted with the larger vessel because there was far less sea spray.  Our enthusiasm was short lived, however:  En route to our first destination, Mexico Rocks, we were treated to a brief rain shower.  At the speed we were traveling, the rain felt like a hail of bullets. Mexico Rocks, named after the adjacent shore, is a mid-lagoon, patch-reef system home to a wide diversity of marine wildlife. Montastrea annularis (boulder star coral) dominates the limestone-based geology.  We encountered a countless diversity of marine organisms, the highlights of which were southern stingrays, Caribbean reef squid, a green moral eel, gray and queen angelfish, colorful tube sponges, and over a dozen species of damselfish.  After the group snorkel, we were invited to explore the site on our own, being mindful to adhere to the buddy system. 

Our second location was at the mouth of a limestone cave system that stretches many miles deep into the mainland.  Some of us swam down 15 or more feet and gazed into the dark interior.  There were Caribbean giant anemones, a couple invasive lionfish, spiny lobsters, and many dozens of fish positioned upside-down with their bellies against the roof of the cave.  Of course we were obedient and did not swim into the cave: Dr. Smith would have killed us. The final snorkel site of the day was Playa Blanca, a shallow back reef where we broke into groups of 2-4 and tested each other’s ability to identify organisms. We discovered (one of tactility) the infamous fire coral in addition to a sneaky juvenile spotted moral eel. We concluded our day at the compound with a study hour and that awesome feast of spaghetti and meatballs! (Written by Garrett Faucette and Cassie Hensel).
