My new favorite hobby on the island is walking along research beach, where there is a strip of rocks leading to shark bay. these rocks are home to a lot of little species, like Chitons and swift-footed crabs. I like to pick up different shells and see if there are hermit crabs in them, but i give cone shells a wide berth, since they can send out poisonous harpoons. While walking i also saw a Portuguese Man O War, about the size of my thumb, stuck to a rock.
For out lab today we recorded transect lines of fish. We had to swim out into the lagoon at high tide, which wouldn't be so complicated if it weren't for the wind blowing waves over us as we tried to swim out the weighted lines. Luckily my partner, Sean, is much better and diving than me and we were able to record the footage we needed, though I swallowed a mouthful of seawater. We went back later at low tide and were able to wade through the water. We then compared the fish abundance and found that fish were much more abundant at high tide, since there is much more three dimensional space to move around in during high tide. During low tide they hide under the corals since sharks prefer to hunt at low tide.
The more you know.
