Coral graveyard and crab shenanigans (09/06/22)

Leave a comment

Hi y’all, it’s Liliana again.

I am completely exhausted right now so lets hope that I can write something coherent. We started early again at 6:30, and I hate to say it but waking up that early is becoming more normal. We practiced using our transects and quadrants on land before we formed our research question and went out on the water. This time we stuck to the sea grass and swam through it looking for a specific green algae, penicillus. Each group of two with a total of seven groups swam at least 100 feet out, looking to see how many we could find in a 2×4 area every 10 feet, in the end despite all the ground covered we did not find that many. My group only found two, but we found some other exciting stuff instead like an upside down jelly! And more relevant to my taxon we found a crab next to the upside down jelly, but it was very dead and I didn’t want to get close enough to the jelly to see what the crab was. We wrote our findings and made a group poster and presentation about our mini experiment.

After lunch we went to the coral graveyard, which is great for identifying coral species since you can get a really close look at all the parts and how it looks underneath the living tissue.

After that I got to present my lecture on lionfish/invasive reef species, and my years long mission to eat a lionfish, and I hope that this trip will finally be my chance, since there are many lionfish on this reef that need to be removed.  Today was interesting in terms of crab behavior.

On my way to the bathroom I spotted this hermit crab dragging a small lizard across the ground into a hole.

We also discovered that the hermit crabs like coconut, they’ve been swarming the area where the children were cracking and eating coconuts.

Anyways, it’s time for me to go to sleep, I am exhausted and need all my rest before tomorrow.

Day 2: Mosquito Magnet

2 Comments

Today started off early with a yummy banana pancake breakfast and then our first snorkel excursion at 8am. We finally got to break out all of our fancy TFB gear (snorkels, masks, fins, diving skins) and use them! To get off of the dock and into the water, I just sat down and shimmied off, directly into a school of small fish. We then swam over some sea grass to a path reef and I was able to see sooo many organisms. There was Brain Coral, Common Sea Fans, Corky Sea Fingers, also lobsters, French Angel Fish, Lion Fish (!!), and an anemone! Apparently we might go out and hunt for Lion Fish since they are invasive and have them for a meal. I also was able to spot a piece of Laurencia spp. floating in the water and a lot of Spryidia filaments on the rocks. I’ll spare you from my extremely blurry photos but I’ll get the hang of this camera soon.

After we got back on land we made one of our field tools called a Quadrate which we will use as a measuring device to collect data. Then after lunch, we headed back into the water but this time through the Mangroves of Death (cue dramatic music). Where does this name come from you ask? The mosquitos. We literally had to run for a few minutes to try to dodge as many mosquitos as we can in order to go through the mangroves. It was totally worth it though. We made it to the shoreline and had to “stingray shuffle” through the seagrass because it’s their favorite habitat and you want to avoid surprising them. At these patch reefs I saw Yellow Snapper, baby Blue Tang (which look just like yellow surgeon fish), Royal Gramma (shout out to my dad’s fish tank), damselfish, a sea urchin (super cool), and similar coral as the patch reef from earlier in the day.

We chose to swim back in order to avoid the MOD once again, and saw even more cool things – sharks, sponges, and stingrays (oh my!). It was actually very nice to have more time in the water and watching the sea grass was quite meditative.

For the rest of the day we had taxon briefing and a topic lecture which will all help with more identification tomorrow!

Day 10

Leave a comment

Today was our first complete day on the reef. I can’t really put into words how lovely it is here. Sure I have sand on just about every surface of my body, but I am thoroughly enjoying my time here. The day was centered on two tools: the transect and quadrat.

First, we tried to quantify the percent cover of crab holes on the paths around the station (using the quadrats/transect on land). Honestly, my group did not get that much data (only one half of a square was covered over our entire transect).

This was then scaled up for our afternoon activity, transects searching for two geneses of green algae (Halimeda and Penicillus). We were trying to answer a similar question to the percent crab hole cover. We wanted to know if Halimeda or Penicillus would be more abundant in the sea grass bed.

Again, my groups struggled to find anything on our transect, with it being placed in some of the thickest grass. Either way, our data showed a significantly higher amount of Halimeda over Penicillus.

On the reef I continued to see Gorgonian sea fans, as well as whips and rods. I think that the future challenge that I will face is distinguishing between soft corals that are branching, yellow/brown, with them all being of similar morphology. Tomorrow on the more distant reef, I hope to see more.
