There is no doubt

but that fishes have the sense of taste, for a
great number of them delight in special flavours; and fishes freely
take the hook if it be baited with a piece of flesh from a tunny or
from any fat fish, obviously enjoying the taste and the eating of food
of this kind. Fishes have no visible organs for hearing or for
smell; for what might appear to indicate an organ for smell in the
region of the nostril has no communication with the brain. These
indications, in fact, in some cases lead nowhere, like blind alleys,
and in other cases lead only to the gills; but for all this fishes
undoubtedly hear and smell. For they are observed to run away from any
loud noise, such as would be made by the rowing of a galley, so as
to become easy of capture in their holes; for, by the way, though a
sound be very slight in the open air, it has a loud and alarming
resonance to creatures that hear under water. And this is shown in the
capture of the dolphin; for when the hunters have enclosed a shoal
of these fishes with a ring of their canoes, they set up from inside
the canoes a loud splashing in the water, and by so doing induce the
creatures to run in a shoal high and dry up on the beach, and so
capture them while stupefied with the noise.
