Description
An account of the resource
The prenatal development of bowhead whales is poorly known, and no complete ontogenetic series exist. However, the available embryos and fetuses elucidate aspects of the development of the species, as well as that of all of mysticetes in general, and demonstrate the role of heterochrony in development. For instance, hair on the face of bowhead whale embryos develops at the same ontogenetic stage as it does in terrestrial mammals, even though body hair never develops. The absence of teeth characterizes all modern baleen whales, but bowhead whale fetuses initiate teeth around the same time as land mammals, to then resorb them in the fetal period. Baleen forms after that, late in the fetal period.

Description
An account of the resource
The postcranial skeleton of bowhead whales was described in detail more than 100 years ago. The musculature of bowheads has not been studied in detail but matches that of other mysticetes in general features. In this chapter, we focus on some aspects of the skeleton that differs from that of other cetaceans. First, the skeleton of bowheads changes with ontogenetic age. Some of these changes are gross-morphologically, while others are biochemical and histological. Several are related to the life history of the species. Our discussion focuses on the changes in the morphology of the cervical vertebral column, the ontogenetic variation in carpals, and the variation in the hind limb. Individuals with external hind limbs occur infrequently, but there is a great variation in the size of ox coxae, femur, and tibia.
