On the evolution of baleen whales
Science, 2018Evolutionary 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.

A newly discovered species of living baleen whale
Nature, 2003In the late 1970s eight Balaenoptera specimens of unknown identity were caught in the lower latitudinal Indo-Pacific waters by Japanese research whaling vessels. The combination of the allozyme patterns and physical maturity of the eight specimens separated them from all acknowledged Balaenoptera species.

Multiple origins of gigantism in stem baleen whales
The Science of Nature, 2016Living baleen whales (Mysticeti) include the world's largest animals to have ever lived-blue whales (Balaenoptera musculus) can reach more than 30 m. However, the gigantism in baleen whales remains little explored. Here, we compiled all published stem mysticetes from the Eocene and Oligocene and then mapped the estimated body size onto different ...

During the night of 13 to 14 March, the Nautilus continued on its route southwards. I thought that once at Cape Horn it would set sail for the west, in order to head for the seas of the Pacific and thus complete...

Right Whale Feeding and Baleen Rattle
Journal of Mammalogy, 1976Surface and subsurface feeding behavior of right whales, Eubalaena glacialis (Borowski, 1781), has been observed in Cape Cod waters since 1956. During surface feeding the whales follow discrete rows of concentrated plankton, and in subsurface feeding they also appear to be feeding on specific patches of food at particular depths and localities.

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.

II.—The Baleen Whales of the South Atlantic
Proceedings of the Royal Society of Edinburgh, 1915Whaling companies have for some years successfully conducted a whale fishery off the shores of the South Shetlands, Graham Land, South Orkneys, and South Georgia, where the waters of the Antarctic mingle with the South Atlantic Ocean.

Building a Virtual Model of a Baleen Whale
2011Abstract : This long term goal of this research is to eventually CT scan an adult baleen whale. The research effort will be subdivided into three phases. The current activity only covers Phase 1, the design and testing phase. No marine mammal specimens are needed in this initial design and testing phase.
