Furthermore,

there are some strange creatures to be found in the
sea, which from their rarity we are unable to classify. Experienced
fishermen affirm, some that they have at times seen in the sea animals
like sticks, black, rounded, and of the same thickness throughout;
others that they have seen creatures resembling shields, red in
colour, and furnished with fins packed close together; and others that
they have seen creatures resembling the male organ in shape and
size, with a pair of fins in the place of the testicles, and they aver
that on one occasion a creature of this description was brought up
on the end of a nightline.

So much then for the parts, external and internal, exceptional and
common, of all animals.
