Today we started and completed a whole new experiment. To look at sea urchin community structure (and the indications it may have for herbivory and reef health), we went out and collected sea urchins in a bucket and recorded the species and diameter of each urchin.
During the search, I noticed several new hydroids! I saw what I believe to be a lot of Box Fire Coral (Millipore squarrosa), which is the third and last species of fire coral that I found to be common in the Caribbean.
I also spotted some Kirchenpaueria halecioides, a small hydroid that gets up to about one inch tall (see photo below) in addition to a possible Feather Bush Hydroid (Dentitheca dendritica).
Much later in the day, we got back in the water for a night snorkel. It was fun, but my dive light went out, and we were all way too close to each other – I think we were all paranoid about losing the group. When I got back, I found a tiny little fish inside my swimsuit. It must have somehow made its way into my skintight dive skin and swimsuit, but nothing can surprise me at this point.
