Cranial asymmetry in odontocetes: a facilitator of sonic …
2023年10月1日 · Skull asymmetry may allow hypertrophy of the right vocal apparatus to emit louder sounds. High asymmetry may permit powerful clicks under right-sided lateralized production. Thus, cranial asymmetry in odontocetes seems adaptative by allowing more space for sound-generating structures for echolocation.
Wonky whales: the evolution of cranial asymmetry in cetaceans
2020年7月10日 · Unlike most mammals, toothed whale (Odontoceti) skulls lack symmetry in the nasal and facial (nasofacial) region. This asymmetry is hypothesised to relate to echolocation, which may have evolved in the earliest diverging odontocetes.
Ecomorphology of toothed whales (Cetacea, Odontoceti) as
2023年1月25日 · Odontocete skull morphology exhibited a significant phylogenetic signal, with skull size showing stronger signal than shape. After accounting for phylogeny, significant associations were detected between skull size and biosonar mode, body length, brain and body mass, maximum and minimum prey size, and maximum peak frequency.
Cranial asymmetry in odontocetes: a facilitator of sonic ... - PubMed
2023年8月6日 · In this study, we investigated how cranial asymmetry varies across odontocete species both in terms of quality (i.e., shape), and quantity (magnitude of deviation from symmetry). We investigated 72 species across all ten families of Odontoceti using two-dimensional geometric morphometrics.
Unlike most mammals, toothed whale (Odontoceti) skulls lack symmetry in the nasal and facial (nasofacial) region. This asymmetry is hypothesised to relate to echolocation, which may have evolved in the earliest diverging odontocetes.
The ontogeny of asymmetry in echolocating whales
2022年8月3日 · Extreme asymmetry of the skull is one of the most distinctive traits that characterizes toothed whales (Odontoceti, Cetacea). The origin and function of cranial asymmetry are connected to the evolution of echolocation, the ability to use high-frequency sounds to navigate the surrounding environment.
Wonky whales: The evolution of cranial asymmetry in cetaceans
2020年7月10日 · Background: Unlike most mammals, toothed whale (Odontoceti) skulls lack symmetry in the nasal and facial (nasofacial) region. This asymmetry is hypothesised to relate to echolocation, which may...
Asymmetry of the nasofacial skull in toothed whales (Odontoceti)
2016年12月1日 · In this study, the nasal asymmetry of odontocetes (toothed whales) was analyzed morphometrically by placing landmarks on photographed nasofacial skulls from 12 different species and genera that...

Breaking symmetry: The marine environment, prey size, and …
2007年5月21日 · Skulls of odontocetes (toothed whales, including dolphins and porpoises) are typified by directional asymmetry, particularly in elements associated with the airway. Generally, it is assumed this asymmetry is related to biosonar production.
