Note 18 — Chapter XXIV · THE BOTTLENOSE PORPOISE IN CAPTIVITY
Reading edition
I do not believe that because the porpoise would not seize a fish suspended above the water, it is evidence that it could not see it. Not being accustomed to take its food out of the water, the animal probably did not know what the fish was. A wounded porpoise which I kept alive for some time on a ship in the Pacific could see my hand if it was brought within a few feet of its eyes. R. C. A.
