Day 3: A Coconut Paradise

Feeling like a true field biologist! Today we practiced using our quadrates and trisects, first on land and then in the water. For the water experiment, the whole group came up with the research question: how does the density of the green algae Penicillus changes the further you go from shore? We also brainstormed a hypothesis (that they’d become less abundant) and a method to carry out our question. In the end, our hypothesis was wrong, but it was still really fun to be able to look closer into the seagrass and find all of the other organisms that reside in it (corallomorphs, anemones, and conchs).

Before, as we were working on our experiments and waiting for everyone to be finished, we were all treated with 10/10 service from Dr. Correa and Dr. Solomon’s kids Calliou and Nayala. I learned how to husk a coconut and also how to get the water out from it. I now believe that I could most definitely survive on a deserted island. No doubt.

After lunch, we went to the wet lab and worked on our group poster about the green algae experiment (during which we were graciously treated with even more delicious fresh coconut from Calliou and Nayala) and  then presented it to Dr. Correa and Dr. Solomon (we totally aced it too ;)). We then went out to Dr. Correa’s favorite spot in the whole entire world: the Coral Graveyard. Once you get there, you can totally understand why too. Here, it was a section of the old reef that re-mineralized and all of the coral skeletons are super clear and really easy to identify as they are all now stone. This also includes the conch shells which I thought was pretty crazy. Some corals that we identified include Fire Coral, Symmetrical Brain Coral,  and Pillar Coral (which sadly isn’t very common anymore). Also! I was able to see some Crustose Coraline Algae (my taxa) mineralized. It was super cool to be able to see the skeleton of the hundreds of pieces corals before they corrode into sand, something that you don’t get to see everyday.

Lionfish Guts

May 27, 2019

Today, we cleaned up marine debris on the island. Part of the experiment was looking at the amount and composition of trash in different areas of the island, so three brave souls (Kaela, Amy, and Kelsey) volunteered to cover the Mangroves of Death.

After going through the collected marine debris, Scott brought out some coconuts, and we got to try fresh coconut water and coconut meat.

In the afternoon, we dissected the lionfish that Scott and Herbie speared a couple days ago. This involved estimating sex and reproductive maturity of the fish and then identifying its different organs. When Liz and I opened the stomach of our lionfish, we found a whole undigested fish in it! We identified it as a juvenile slippery dick.
