Chap. 3 (4.) — The Largest Animals That Are Found in Each Ocean
The largest animals found in the Indian Sea are the pistrix and the balæna; while of the Gallic Ocean the physeter2215 is the most bulky inhabitant, raising itself aloft like some vast column, and as it towers above the sails of ships, belching forth, as it were, a deluge of water. In the ocean of Gades there is a tree,2216 with outspread branches so vast, that it is supposed that it is for that reason it has never yet entered the Straits. There are fish also found there which are called sea-wheels,2217 in consequence of their singular conformation; they are divided by four spokes, the nave being guarded on every side by a couple of eyes.
