I’ve come out of day 12 of this trip with a whole new appreciation for land. We leveled up on our boating expedition today by traveling outside the reef crest and the calm waters of the Glover’s Reef. The morning’s topic was reef zonation, so we ventured into the open ocean to check out the coral ecosystems beyond the atoll. In these deeper reefs, I saw a lot of larger herbivorous fish, especially terminal phase parrotfish. I was able to identify conspicuous males of the striped parrotfish (Scarus croicensis) and some female/primary male stoplight parrotfish (Sparisoma viride). But the real excitements of the morning were our carnivore sightings; we watched a giant spotted eagle ray fly across the benthos and a nurse shark glide through mountains of coral.
However, the choppy waves weren’t as appealing from the boat as they were on the reef. Thankfully every TFB came out of this experience unharmed, but I think a few of us might be jumping ship from team surf for the moment (sorry, Adrienne).
The afternoon’s snorkel was spent on back reef just in sight of the island, ending our boating adventures for the day. Though we couldn’t have been in more than 3 feet of water, the mix of seagrass and corals produced a scene reminiscent of Finding Nemo (sorry again, Adrienne). I swam right
past a whole school of ocean surgeonfish (Acanthurus bahianus) and found tons of small dusky damselfish (Stegastes fuscus) tending to their algae gardens. Since these reefs were much smaller, I didn’t see any large parrotfish here, but I did find a number of tiny juvenile striped parrotfish (Scarus croicensis)—these seem to be common on shallower reefs. But the primary objective on the back reef was spearing lionfish, an invasive species from the Indo-Pacific. We managed to collect quite a few specimens for studying (and cooking) later in the week.
All in all, today gave me a new appreciation for both the ocean’s beauty and the wonderful stability of turf.
