Regina Eisert was standing on sea ice on the coast of Antarctica when the young mammal approached her camera.
The whale can be seen opening its mouth and chewing on some toothfish before it swims away.
Ms Eisert, who is based at the University of Canterbury in New Zealand, had been studying Type-C killer whales to better understand the population size, where they live and what they eat.
