This morning we were ready to go trawling at Shag Rocks.
The first trawl was in the water early, and throughout the day we completed a total of 11 trawls. As you might guess, we were pretty tired! But we got all the organisms we’d hoped to find.
One of the targets we were after was a seastar called Porania antarctia. Because this was the last one were looking for, every time we found one, spontaneous cheering broke out.
Also, during the evening we had a visit from two birds not often seen in this part of the world. Two egret-heron type birds came and sat on the deck for a while. The swells were getting a bit bigger, so every time water washed across the deck, the birds got swept along as well.
I wonder what they were doing here? Can any bird enthusiasts tell us about them?
One of the neatest finds of the day was a strange one. In one of our trawls, we picked up a vertebrate bone of sorts. And since Greg was one of the people who first described Osedax, bone-eating worms, he was very keen to take a close look. And indeed, there were some Osedax growing out of the bone. Cool!
