Large Mature Bull Sperm Whale | Physeter macrocephalus

An enormous mature bull sperm whale (Physeter macrocephalus) approaching 20m in length. This imposing bull approached to within two to three meters from me. At this proximity, the whale clanged loudly, which caused my ear canals to clear, as if I had executed a Valsalva maneuver. The mature male was associated with a group of females, at one point surfacing adjacent to a mature female. The male easily exceeded 1.5x the length of the female. Note the substantial scarring on the whale’s forehead, likely indicative of interactions with other males.
