[Excerpt from the notes of a natural philosopher aboard a whaling ship]
Remarkably, each specimen I had the pleasure of studying during the voyage possessed some minor variance in physiology. On the second leg of the trip, east of Tyvia, the crew hauled aboard a female, some 42' in length. I estimate she weighed 35 tons and the ship sat low, rocking side to side through the night with her thrashing.
By candlelight, I took her apart, sketching and taking notes. Against her bellowing, I cut into the mass of tentacles around her mouth. Within I found row upon row of teeth and a baleen running along the upper jaw. Through this broom-like structure, I assumed she filtered food from the water that was too small to be chewed.
