So we had a fright of our lives today whilst working on the support cables. The divers had reported seeing something large swimming through the water. Unfortunately the water is so murky that they could only see a vague dark outline.
It seems their activities in the water had attracted whatever it is, because not long after they had finished their task the creature came at one of the walkways with surprising speed knocking into it and causing us to stumble. Whilst we once again failed to get a good look at the creature given the water, we did see that it seems to have a kind of shell with what looks like long-grass growing out of it.
It swam away shortly after knocking into the walkway but it wasn’t the last of the incursions. Several times throughout the day it (or others of its species) continued to harass us. As a result work on the bridge did not make as much headway as I had wanted.
Tomorrow I plan on taking the boat out in the direction the creature swam off to, perhaps I can find a means to study it. I do not even know why it attacks. Are we infringing upon its domain? Is it carnivorous?
