Description

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.
