Sharks

The sharks are residents of the aquarium’s main tank, defined in the novel less by individual traits than by their ceaseless movement in captivity. Their repeated laps become a point of recognition for Tova, who understands the pressure of being unable to stop moving without risking breath.

Life in the Aquarium

During her customary evening round, Tova pauses to bid the sharks good night. She thinks of them as trapped in never-ending circuits, their movement imposed by the confines of the tank. Her response is not simply a keeper’s routine: she feels empathy for creatures whose continued motion seems bound to survival.

Feeding and Contrast

The sharks receive fresh grouper, while Marcellus is fed mackerel, halibut, and especially herring, often defrosted and sometimes still partly frozen. Marcellus regards the sharks as dull and their better meal as an undeserved reward, a judgment that reveals his own resentment of aquarium life and its rationed food. The contrast makes the tank’s feeding arrangements visible through competing animal perspectives rather than presenting captivity as a neutral routine.

The Stolen Halibut

On one of his nighttime escapes, Marcellus props open a door with a stool and raids fresh halibut chunks Terry had left beneath the main tank’s hatch. The food was presumably intended as breakfast for the sharks. Marcellus dismisses the theft with the observation that the sharks scarcely distinguish night from day; his brief freedom is pleasurable, but the failed door leaves him unable to trust that escape route again.

Narrative Significance

The sharks’ circling gives Tova a concrete image of confinement that resonates with her own understanding of what it means to keep moving. Yet their presence also remains materially specific: they occupy the main tank, receive fresh grouper, and nearly lose a breakfast to Marcellus’s opportunistic raid. Their limited portrayal preserves a contrast between the human observer’s compassion and the octopus’s sardonic, self-interested view of fellow captives.
