The ganoids of which the sturgeon and garpike are examples, with heavy plates or scales.
The garpike as he saw it, with amplifications from the Indians as they had seen it, gave him the subject for a good fish story.
These fishes in many respects resemble the garpike in habits.
Such fishes as the garpike and the bowfin have lung-like air-bladders and gulp air from the surface of the water.
These are found in the garpike and in many genera of extinct Ganoid and Crossopterygian fishes.
In the garpike the vertebræ are convex anteriorly, concave behind, being joined by ball-and-socket joints (opisthocœlian).
These creatures have been often called ganoids, but with the true ganoids like the garpike they have seemingly nothing in common.
