Although it’s been only a mere four days since our arrival here in Jamaica, project ideas have been discussed and developed—research set in motion. Proposals have been written on topics ranging from sponge diversity and coral diseases to inking of spotted-sea hares (Aplysia dactylomela) and the notoriously aggressive Dusky damselfish.

After a whirlwind of lectures on different types of algae (Rhodophyta, Chlorophyta, Phaeophyta, and Turf Algae), ecology, oceanography , reef inverts, tropical fish, sponges, coral (Phylum Echinodermata, Class astroidea), global warming, and history of Jamaica’s reefs in the past four days, we’ve finally made it through ‘spurs’ of stomach squeezing studying. We’ve learned the secret behind Wendy’s mouth-watering thick milk shakes lies in *Carrageenan, a thickening substance derived from some of the oldest eukaryotes in the world: red algae aka Rhodophyta. We’ve made our collection presentation powerpoints. We’ve taken our first, and last exam-practical. We’ve cleared out our wet lab species collection tank.

We’ve cleared our desks of index cards, highlighters, and species identification books.

Just as the King Helmet (Crassis tuberosa), Variegated Sea Urchin (Lytechinus variegates), Sea Cucumber (Holothuria mexicana), Indian Sea Egg (Tripneustes ventricosus), and Common Comet Star (Linckia guildingii) anxiously await escape from the muted halls and back into Discovery Bay, as do we.

We release them in hopes that they will recover much like we had after our study escapades (ie. volleyball). The sun is shining, the waters are calm, and the tide is low.

—Mei sigining and diving off into the marine world, a whole new world—waiting and beckoning our attention, curosity, and research.

*side note: [This phycocolloid Carrageenan, specifically found in the red algae species called Eucheuma cottonii and Eucheuma spinosum, is not only used in ice cream, pudding, and food, but toothpaste as well. Some other phycocolloids from red algae include agar, which can surprisingly cost up to $1200 per ton.]
