This fourth large family of bony Fishes includes the Perch family, which
is altogether a fresh water Fish; and many curious species which are
found in the sea—like the Weevers, Mullets, Gurnards, Labrus, Frog-fish
and Sword-fish. The well known Mackerel family is also included among
the Fishes with spiny fins, with the Tunny and the curious Archer-fish.
The Weevers are a good type of these spiny-finned Fishes. They bury
themselves in the sand, and are dangerous to the fishermen because of
the serious wounds which they inflict with their spines.
