Perhaps he died of mortification from such an extraordinary unfishlike experience. ❋ Mrs. T. P. O (1914)

The creature shivered and collapsed at that contact in the most unnatural, unfishlike manner; and Luigi drew up, to his amazement, a fragment of a lady's dress -- to wit, a short length of sky-blue CREPE DE ❋ Norman Douglas (1910)

Brace glanced after it, to see it for a few moments as the line was allowed to run, the silvered unfishlike piece of metal beginning to spin and, as it receded farther from the boat, to assume a wonderfully lifelike resemblance to a good-sized roach swimming pretty fast. ❋ George Manville Fenn (1870)

Upon the top story of the same building were preserved in a rough museum various other strange forms, not all from Woods Hole waters; the remora, or sucking fish, that fastens on sharks and becomes a constant passenger enjoying a free ride, specimens of which were often in the Aquarium; the deal-fish, which alone among its tribe has a long slim fin projecting upwards from the tail almost at right angles to it; the blenny, whose facial expression has caused it to be known as the sarcastic blenny; the graceful sea-horse, who swings on seaweed with a prehensile tail like that of a monkey -- and the male of which hatches the eggs instead of the mother, and not the least extraordinary, the three-cornered trunk-fish whose front view is the most unfishlike apparition possible. ❋ Francis Rolt-Wheeler (1918)

Is it for an end so cruel as this, that I have taken such care of myself upon the southern shores of this unworthy continent, feeding with a tasteful choice and epicurean delicacy amid the marine vegetation that adorns its milder latitudes, and plumping and beautifying myself into this admired shape, and all to gratify at last the cormorant appetite of this unfishlike animal, and decorate, with my remains and memory, a mere steam-boat breakfast! ❋ Various (1840)
