Bowhead whales (Balaena mysticetus) have adopted growth and reproductive strategies to
survive in a challenging environment where no other mysticete whales reside. They grow …

Sperm whales' reproductive strategies are centered around their extreme sexual
dimorphism, both in morphology and behavior. Females are much smaller than males and …

An understanding of the functional morphology of the bowhead whale continues to have
significance for population management. This chapter first examines the anatomical features …

The bowhead is circumpolar but exclusively Arctic in distribution, whilst the pygmy right is
only found in the Southern Hemisphere north of the Antarctic Convergence and in water …

Bowhead whales ram feed by slowly moving forward, often termed skim feeding. This occurs
at the surface, in the water column, and at the bottom, even to several hundred meters depth …

Given the huge size of their testes (approximately 1,000 kg), it has been hypothesized that
North Atlantic right whales (Eubalaena glacialis) have a mating system that is based upon …

Abstract Beaked whales (Ziphiidae), with 24 currently recognized species, are arguably the
least known large animals on the planet, despite being widespread and at times abundant …

Since the mid-1970s, study has focused on reproductive biology of female bowhead whales,
while little has been described for males. This study evaluates testicular morphology (mass …

While a variety of reproductive tactics are readily witnessed in odontocetes, such behaviors
can be far more elusive in baleen whales and in some cases are yet to be observed. This …

North Atlantic and southern right whale social interactions and sexual behavior have been
studied for decades. Understanding whale mating systems can inform about many aspects …
