While not the longest animal overall, their bulk is staggering. Males experience a prolonged growth phase, continuing to gain length and mass well into their 30s.
Size Differences By Ocean Region: How Sperm Whale Dimensions Vary Across the Seas
The disparity between the sexes is pronounced, with males achieving lengths that can be 30% greater than females. The sheer volume contained within that head, primarily composed of spermaceti oil, is a primary factor in the species' overall girth and density.
Even with contemporary verification, encounters with males exceeding 55 feet remain rare and awe-inspiring events for researchers. Furthermore, their weight is comparable to that of approximately 8 to 10 adult elephants.

This extended growth period results in individuals that accumulate significant size over a lifetime of oceanic travel. This variation is a result of factors including water temperature, food availability, and genetic divergence between populations.
