Occurrence of Anisakis physeteris Baylis, 1923 and Pseudoterranova sp. (Nematoda) in Pygmy Sperm Whale Kogia breviceps (De Blainvillei, 1838) (Physeteridae) in Northeastern Coast of Brazil [PDF]

Memorias do Instituto Oswaldo Cruz, 1998
An adult male pygmy sperm whale, Kogia breviceps (De Blainvillei, 1838) (Physeteridae), 2.73 m long was found stranded on Cacimba do Padre beach, Fernando de Noronha archipelago (3 degrees 51'S; 32 degrees 25'W), Brazil on 2 May 1987. At necropsy, nematodes were collected from the stomach, fixed in 70 GL alcohol and cleared in beechwood creosote. Their

Drivers of Viral Diversity and Sharing in Marine Mammals. [PDF]

Mol Ecol
ABSTRACT Knowledge of viral infection in marine mammals, a group severely threatened by human activity, is largely limited to the pathology and epidemiology of few endemic viruses. The recent emergence in marine mammals of high‐consequence viruses, such as H5N1 avian influenza and rabies, underscores the importance of understanding the ecology of viral

Three-Dimensional Vascular Structure of Caudal and Dorsal Fins of a Dwarf Sperm Whale. [PDF]

Ecol Evol
This 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.

Determinants of Ascaridoid Nematode Infection and Anisakis-Related Zoonotic Exposure Risk in Eastern Mediterranean Gadiformes Fishes. [PDF]

Transbound Emerg Dis
Larvae of ascaridoid nematodes, particularly Anisakis spp., are common parasites of commercially important marine fishes and may represent a zoonotic hazard following ingestion of raw or undercooked seafood. We investigated the ascaridoid fauna of the sympatric European hake (Merluccius merluccius) and greater forkbeard (Phycis blennoides) from the ...

Using multivariate generalized linear latent variable models to measure the difference in event count for stranded marine animals [PDF]

Global Journal of Environmental Science and Management, 2021
BACKGROUND AND OBJECTIVES: The classification of marine animals as protected species makes data and information on them to be very important. Therefore, this led to the need to retrieve and understand the data on the event counts for stranded marine ...

How is the third jaw joint in whales different? Diverse modes of articulation between the jaws of whales. [PDF]

J Anat
This study conducts the first comprehensive morphological investigation of the mandibular symphysis in whales. Using gross anatomical observation and CT cross‐sectional data, we describe diverse joint morphologies across 74 extant and fossil cetacean taxa. Toothed whales exhibit unfused, partially fused, or fully fused symphyses.

How large should whales be? [PDF]

, 2013
The evolution and distribution of species body sizes for terrestrial mammals is well-explained by a macroevolutionary tradeoff between short-term selective advantages and long-term extinction risks from increased species body size, unfolding above the 2g

La hiperdiversificación de Physeteroidea (Cetacea: Mammalia) del Mioceno tardío en el Pacifico Sur, nuevos fósiles del área de Sacaco, Arequipa, Perú

Revista Peruana de Biología, 2020
Los cachalotes (Physeteroidea) son un grupo de cetáceos con una ecología restringida en la actualidad. Las tres especies actuales son el remanente de un grupo que alcanzó su máxima diversificacion durante el Mioceno, incluyendo cinco especies simpátricas
