Beyond thermoregulation: metabolic function of cetacean blubber in migrating bowhead and beluga whales.

The processes of lipid deposition and utilization, via the gene leptin (Lep), are poorly understood in taxa with varying degrees of adipose storage. This study examines how these systems may have adapted in marine aquatic environments inhabited by…

Evolutionary aspects of the development of teeth and baleen in the bowhead whale.

In utero, baleen whales initiate the development of several dozens of teeth in upper and lower jaws. These tooth germs reach the bell stage and are sometimes mineralized, but toward the end of prenatal life they are resorbed and no trace remains…

Structure of the external auditory meatus of the Bowhead whale (Balaena mysticetus) and its relation to their seasonal migration.

The external auditory meatus (EAM) in many species of mysticete whales is filled with a waxy ear plug. Though this lamellated structure is often used to age a whale, its formation and development remain undescribed. It is thought that growth layer…

An analysis of von Economo neurons in the cerebral cortex of cetaceans, artiodactyls, and perissodactyls

Von Economo neurons (VENs) are specialized projection neurons with a characteristic spindle-shaped soma and thick basal and apical dendrites. VENs have been described in restricted cortical regions, with their most frequent appearance in layers III…

Highlights of Cetacean Embryology

The embryology of cetaceans documents features that elucidate the interaction between form and function in modern species, as well as their evolution from extinct ones. Prenatal specimens of the dolphin Stenella attenuata demonstrate critical aspects…

Olfaction and brain size in the bowhead whale (Balaena mysticetus)

P>Although there are several isolated references to the olfactory anatomy of mysticetes, it is usually thought that olfaction is rudimentary in this group. We investigated the olfactory anatomy of bowhead whales and found that these whales have a…

Allometric patterns of fetal head growth in mysticetes and odontocetes: Comparison of Balaena mysticetus and Stenella attenuata

Unlike other mammals, odontocetes and mysticetes have highly derived craniofacial bones. A growth process referred to as "telescoping" is partly responsible for this morphology. Here, we explore how changes in facial morphology during fetal growth…

Chapter 7 - Life history, growth, and form

Bering–Chukchi–Beaufort Sea bowhead whales are born at about 4.2m in length and 1000kg, in lead systems along the NW Alaskan coast. Bowheads in the other northern stocks are also born in ice-covered seas. Maximum body lengths (standard measure) can…

Chapter 8 - Prenatal development

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…

Chapter 9 - Anatomy of skull and mandible

The skull of the bowhead whale is composed of all the bones commonly found in mammals, although the shape of these bones is far from ordinary. Features related to feeding dominate the skull: there are no teeth, and the rostrum is long and curved,…

Chapter 10 - Postcranial skeleton and musculature

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…

Chapter 13 - Female and male reproduction

An understanding of the functional morphology of the bowhead whale continues to have significance for population management. This chapter first examines the anatomical features of the bowhead whale reproductive system, with an emphasis on the female.…

Chapter 18 - Sensory systems

The sensory biology of bowhead whales reflects features both related to their origin from land mammals and adaptations to their current environment, polar seas. There is anatomical and genomic evidence that bowheads have a sense of smell. Their sense…

Chapter 20 - Molecular insights into anatomy and physiology

Bowhead whales are some of the largest animals that occupy the Arctic Circle. Despite the challenges of living and giving birth in icy waters, having huge blubber stores, eating a fat-rich diet, and undergoing arduous migrations, bowheads achieved…

Chapter 33 - Commercial whaling

The commercial hunt of the four stocks of bowhead whales by the nations of Europe and North America commenced in 1540 and came to an effective end at the start of World War I. At that time, all four stocks had been driven to near extinction. Whalers…
