The Humpback's new Songs: Diverse and Convergent Evidence Against Vocal Culture via Copying in Humpback Whales [PDF]
Animal Behavior and Cognition, 2022 Singing humpback whales constantly modify their songs over hours, days, months, and years, throughout their adult lives. Intriguingly, humpbacks appear to vary songs in concert, with most singers in a population producing similar songs at any given time.

Discovery of sexual dimorphism of the laryngeal sac in the common minke whale Balaenoptera acutorostrata. [PDF]
Anat Rec (Hoboken)Abstract Mysticetes, or baleen whales, have an air sac on the ventral surface of the larynx known as the “laryngeal sac.” The primary hypothesis regarding this structure's function is that it is involved in sound production. However, several other functions have been proposed, including air recycling, air storage, and even buoyancy control.

Song Morphing by Humpback Whales: Cultural or Epiphenomenal?
Frontiers in Psychology, 2021 Singing humpback whales (Megaptera noavaengliae) collectively and progressively change the sounds and patterns they produce within their songs throughout their lives.

Oil adsorption does not structurally or functionally alter whale baleen [PDF]
Royal Society Open Science, 2019 Mysticete whales filter small prey from seawater using baleen, a unique keratinous oral tissue that grows from the palate, from which it hangs in hundreds of serial plates.

Mysticete whale abundance and observations of prey associations on the central Bering Sea shelf
J. Cetacean Res. Manage., 2023 Visual surveys for cetaceans were conducted along transect lines in the central Bering Sea in association with a groundfish stock assessment survey from 5 July to 5 August 1999.

ON PLESIOCETUS VAN BENEDEN, 1859 (MAMMALIA, CETACEA, MYSTICETI)
Rivista Italiana di Paleontologia e Stratigrafia, 2021 A new analysis of the “type” Plesiocetus collection established by Van Beneden in the 19th century is performed to provide an updated taxonomy of this genus.

Hydration affects the physical and mechanical properties of baleen tissue [PDF]
Royal Society Open Science, 2016 Baleen, an anisotropic oral filtering tissue found only in the mouth of mysticete whales and made solely of alpha-keratin, exhibits markedly differing physical and mechanical properties between dried or (as in life) hydrated states.

A new archaic baleen whale Toipahautea waitaki (early Late Oligocene, New Zealand) and the origins of crown Mysticeti [PDF]
Royal Society Open Science, 2018 A new genus and species of extinct baleen whale †Toipahautea waitaki (Late Oligocene, New Zealand) is based on a skull and associated bones, from the lower Kokoamu Greensand, about 27.5 Ma (local upper Whaingaroan Stage, early Chattian).

Occipital Ossification of Balaenopteroid Mysticetes [PDF]
The Anatomical Record, 2011 AbstractThe bones of the posterior portion of the mammalian skull often exhibit incomplete ossification of the joints between the bones at the time of birth, with complete ossification at some point after birth. The sequence of ossification of these joints in mysticetes can be used to characterize the relative age in the calf and early juvenile ...
