The animal is hunted whether
young or full grown.
Thus we see that in the case of the creatures above mentioned
their mutual friendship or the is due to the food they feed on and the
life they lead.

Of fishes, such as swim in shoals together are friendly to one
another; such as do not so swim are enemies. Some fishes swarm
during the spawning season; others after they have spawned. To state
the matter comprehensively, we may say that the following are shoaling
fish: the tunny, the maenis, the sea-gudgeon, the bogue, the
horse-mackerel, the coracine, the synodon or dentex, the red mullet,
the sphyraena, the anthias, the eleginus, the atherine, the
sarginus, the gar-fish, (the squid,) the rainbow-wrasse, the
pelamyd, the mackerel, the coly-mackerel. Of these some not only
swim in shoals, but go in pairs inside the shoal; the rest without
exception swim in pairs, and only swim in shoals at certain periods:
that is, as has been said, when they are heavy with spawn or after
they have spawned.
The basse and the grey mullet are bitter enemies, but they swarm
together at certain times; for at times not only do fishes of the same
species swarm together, but also those whose feeding-grounds are
identical or adjacent, if the food-supply be abundant.
