Morphology

jackknife-fish = jackknife + fish (transparent) = jackknife + fish

A straightforward compound: a fish named for its resemblance to a jackknife (shape), so the relation to the base words is directly inferable.

Etymology

Jackknife-fish comes from the English tool jackknife, a small folding 'knife', because the fish's long, upright dorsal fin looks like an open blade. So the name helps you remember this black-and-white drumfish with a sharp, knife-like fin.
