Revista de Biología Tropical, 2023 Introduction: The study of many aspects of cetacean ecology is made possible by identifying individuals through space and time. Humpback whales (Megaptera novaeangliae) can be easily identified by photographing their ventral tail flukes’ unique shape and pigmentation patterns.

First records of Balaenoptera edeni (Cetartiodactyla: Balaenopteridae) in the coast of Oaxaca, Mexico [PDF]
Therya, 2016 To date, few studies have focused on the Bryde’s whale, Balaenoptera edeni, one of the nine species comprising the family Balaenopteridae. This species can be distinguished from other rorquals by the presence of three parallel longitudinal ridges on top of the rostrum, whereas other rorquals possess only one.

Structure of the cerebral cortex of the humpback whale,Megaptera novaeangliae (Cetacea, Mysticeti, Balaenopteridae) [PDF]
The Anatomical Record Part A: Discoveries in Molecular, Cellular, and Evolutionary Biology, 2006 AbstractCetaceans diverged from terrestrial mammals between 50 and 60 million years ago and acquired, during their adaptation to a fully aquatic milieu, many derived features, including echolocation (in odontocetes), remarkable auditory and communicative abilities, as well as a complex social organization. Whereas brain structure has been documented in

Three-Dimensional Vascular Structure of Caudal and Dorsal Fins of a Dwarf Sperm Whale. [PDF]
Ecol EvolThis study examined the vascular architecture in the caudal and dorsal fins of a dwarf sperm whale through X‐ray computed tomography and gross dissection. The analysis provided the first confirmation of two distinct vascular systems in the fins of the family Kogiidae, indicating their presence across Odontoceti species.
