Keeping this cargo meant death—to jettison it meant to make flotsam and jetsam of a world!

The Ciriimian ship was passing in hyperdrive through a classic three-body system, comprising in this case a fiercely white sun circled by a fainter companion and a single planet that swung in precise balance, when the Canthorian Zid broke out of its cage in the specimen hold.
Of the ship's social quartet, Chafis One and Two were asleep at the moment, dreaming wistful dreams of conical Ciriimian cities spearing up to a soft and plum-colored sky. The Zid raged into their communal rest cell, smashed them down from their gimbaled sleeping perches and, with the ravening blood-hunger of its kind, devoured them before they could wake enough to teleport to safety.
Chafis Three and Four, on psi shift in the forward control cubicle, might have fallen as easily if the mental screamings of their fellows had not warned them in time. As it was, they had barely time to teleport themselves to the after hold, as far as possible from immediate danger, and to consider the issue while the Zid lunged about the ship in search of them with malignant cries and a great shrieking of claws on metal.
Their case was the more desperate because the Chafis were professional freighters with little experience of emergency. Hauling a Zid from Canthorian jungles to a Ciriimian zoo was a prosaic enough assignment so long as the cage held, but with the raging brute swiftly smelling them out, they were helpless to catch and restrain it.
When the Zid found them, they had no other course but to teleport back to the control cubicle and wait until the beast should snuff them down again. The Zid learned quickly, so quickly that it was soon clear that its physical strength would far outlast their considerable but limited telekinetic ability.
Still they possessed their share of owlish Ciriimian logic and hit soon enough upon the one practical course—to jettison the Zid on the nearest world demonstrably free of intelligent life.
