And again,

both of gregarious and of solitary animals, some are
attached to a fixed home and others are erratic or nomad.

Also, some are carnivorous, some graminivorous, some omnivorous:
whilst some feed on a peculiar diet, as for instance the bees and
the spiders, for the bee lives on honey and certain other sweets,
and the spider lives by catching flies; and some creatures live on
fish. Again, some creatures catch their food, others treasure it up;
whereas others do not so.
