Beluga whales

Beluga whales become the focus of a mirror-mark experiment that tests whether an animal can use its reflection to inspect a mark on its own body. At Vancouver Aquarium, a beluga repeatedly approaches a mirror, adjusts its position to see the mark beneath its chin, and then swims away. Leon Anawak treats this behavior as evidence of self-awareness, but the episode leaves a careful boundary between recognizing oneself and knowing what another species feels.

The mirror-mark experiment

Anawak has placed a temporary dye dot on the beluga’s lower jaw, in a position it cannot see directly. Two large mirrors are mounted on the reflective walls of the pool, making the reflection the means by which the animal can inspect the mark. Students and journalists watch from the aquarium’s underwater viewing area. On the sixth approach, the beluga swims steadily toward a mirror, turns its white body as it passes the viewing area, then descends until it is level with the glass.

Rather than simply moving past its reflection, the beluga pauses and manoeuvres upright. It turns its head from side to side, apparently seeking the best angle for viewing the dot, and paddles its flippers to hold that position. After inspecting the mark, it loses interest, banks away from the wall, and leaves. The sequence gives the trial its force: the action is directed toward a mark the animal could not otherwise see, not merely toward the mirror or another apparent animal.

Anawak has been careful not to explain the experiment beforehand. He wants the observers to form their own conclusions before he describes the test, in part because he is wary of wishful interpretation. The students and journalists confirm what he has seen. He then identifies the procedure as the mark-test, also called the mirror-test, a method used to examine whether an animal recognizes its reflection as its own image.

What the test is taken to show

Anawak explains that earlier mirror tests had distinguished animals that ignored a reflection or treated it as a rival from chimpanzees that used the mirror to examine themselves. The significance, as he presents it, is not simply that an animal can see an image, but that it can treat the image as information about its own body. He connects this distinction to self-awareness: an animal may feel and react without perceiving itself as an individual distinct from others of its species.

The beluga trials began only a few weeks before the demonstration. Anawak says the animals have been marked six times, twice with a placebo pen. He emphasizes that they were neither rewarded nor trained, and that the mark’s location was changed to guard against results produced by habit or learned routine. The reported contrast is that the whale approaches the mirror and looks for the mark when it is present, but swims away when it is not. On this basis, Anawak concludes that belugas possess a degree of self-awareness comparable to chimpanzees and suggests that whales and humans may have more in common than is usually assumed.

The conclusion is presented as Anawak’s interpretation of observed behavior, not as proof that belugas think or feel exactly as humans do. When a student asks whether the experiment establishes that whales and dolphins have minds, Anawak answers affirmatively. Yet the wider discussion keeps the claim more qualified: at the pool, he wonders whether the beluga experiences or understands emotions like those of humans, and acknowledges that there is no evidence to prove that it does. There is also no proof that it lacks feelings. The experiment addresses recognition of the self through a reflection; it does not settle the separate question of emotional experience.

Behavior, appearance, and restraint

The beluga’s conduct is described through small, observable adjustments: its approach, its vertical posture, the turn of its head, and the effort of its flippers to keep it upright. Those details matter because the scene makes the inference rest on behavior rather than on a human-like expression. The narrator briefly notes that the whale seems almost to smile, but also explains that changes in belugas’ facial expressions enable vocalization and do not in themselves indicate mood. Appearance, therefore, cannot stand in for evidence of an inner state.

After the experiment, Anawak pats the water’s surface. The marked beluga swims over, raises its head, permits him to stroke it, and gives a series of low whistles before disappearing underwater. The contact offers no definitive answer about its feelings; Anawak’s uncertainty remains. The encounter instead places scientific observation beside a direct but limited interaction, without making the animal’s willingness to approach a conclusive emotional statement.

Narrative significance

The belugas give concrete form to the novel’s question of how humans recognize minds beyond their own species. Anawak’s procedure tries to replace projection with controlled observation, while its result challenges the assumption that self-awareness belongs only to humans. At the same time, his caution about emotional interpretation prevents the mirror from becoming a simple human likeness: the animal’s reflection can supply evidence about self-recognition without making its experience transparent.

That distinction also shapes the scene’s account of scientific knowledge. The observers see the same movements, but the meaning of those movements depends on a method, comparison, and limits on what can be claimed. The beluga is not merely a symbol for human feeling; its particular actions are the evidence on which the discussion turns. Yet the final question remains open beyond the test’s reach: self-recognition can be inferred from behavior, while the animal’s subjective life cannot be read directly from the glass.
