Growth of baleen along the baleen rack is constant in balaenopterid whales

Polar Biology, 2021
Werth et al. (Werth et al. Polar Biol 43:707–723, 2020) propose that in all mysticete whales the growth rate of baleen varies with the position they occupy in the mouth. If this were true, comparison between individuals and studies of results of chemical tracers in baleen would be compromised. Here we compile results from previous research conducted in

Paleontological and Developmental Evidence for the Origin of Baleen and the Loss of Teeth in Baleen Whales

The FASEB Journal, 2017
Postnatally, modern baleen whales do not have teeth. Instead, they have hundreds of baleen plates implanted in their upper jaw, and this system is used in procuring food. Fetal baleen whales do initiate the development of several dozens of teeth in upper and lower jaws.

Age Determination in Baleen Whales (Mystacoceti)

Nature, 1965
THE determination of the age of cetaceans is of importance for the organization of a rational exploitation of their stock. Age determination of baleen whales by the layers of ear plugs1,2 does not always give accurate results and raises several technical difficulties3.

Juvenile morphology in baleen whale phylogeny

Naturwissenschaften, 2014
Phylogenetic reconstructions are sensitive to the influence of ontogeny on morphology. Here, we use foetal/neonatal specimens of known species of living baleen whales (Cetacea: Mysticeti) to show how juvenile morphology of extant species affects phylogenetic placement of the species.

On the evolution of baleen whales

Science, 2018
Evolutionary Biology Baleen whales include the largest animals that have ever lived, but their evolutionary history has been difficult to decipher because of conflicting evidence from genes and morphology. Arnason et al. conducted whole-genome sequencing of the blue whale and five other baleen species to reconstruct their evolutionary history in detail.
