Magnificent and glorious, the marlin symbolizes the ideal opponent. In a world in which “everything kills everything else in some way,” Santiago feels genuinely lucky to find himself matched against a creature that brings out the best in him: his strength, courage, love, and respect.
Santiago dreams his pleasant dream of the lions at play on the beaches of Africa three times. The first time is the night before he departs on his three-day fishing expedition, the second occurs when he sleeps on the boat for a few hours in the middle of his struggle with the marlin, and the third takes place at the very end of the book. In fact, the sober promise of the triumph and regeneration with which the novella closes is supported by the final image of the lions. Because Santiago associates the lions with his youth, the dream suggests the circular nature of life. Additionally, because Santiago imagines the lions, fierce predators, playing, his dream suggests a harmony between the opposing forces—life and death, love and hate, destruction and regeneration—of nature.
The shovel-nosed sharks are little more than moving appetites that thoughtlessly and gracelessly attack the marlin. As opponents of the old man, they stand in bold contrast to the marlin, which is worthy of Santiago’s effort and strength. They symbolize and embody the destructive laws of the universe and attest to the fact that those laws can be transcended only when equals fight to the death. Because they are base predators, Santiago wins no glory from battling them.
