LOW-RESIDUE EUTHANASIA OF STRANDED MYSTICETES
Journal of Wildlife Diseases, 2014Euthanasia of stranded large whales poses logistic, safety, pharmaceutical, delivery, public relations, and disposal challenges. Reasonable arguments may be made for allowing a stranded whale to expire naturally. However, slow cardiovascular collapse from gravitational effects outside of neutral buoyancy, often combined with severely debilitating ...

ACOUSTIC COMMUNICATION SIGNALS OF MYSTICETE WHALES
Bioacoustics, 1997ABSTRACT Mysticete (baleen) whales produce a variety of vocalizations and sounds, but relatively few of these have been well described with accompanying behavior. This review concentrates on the vocalizations consistently associated with behavioral interactions or acoustic exchanges between or among conspecifics. These communication “signals” have been

Congenital jugal bipartism in mysticetes
Journal of Zoology, 1969The mysticete jugal (nialar) bone is loosely articulated and hence generally lost fromthe skull during maceration. Inspection of complete mysticete crania reveals a relativelyhigh incidence of congenital jugal bipartism. In such instances the jugal comprises an anterior major, and a posterior minor, element.

Extant baleen whales (Mysticeti) are toothless aquatic predators that use keratinous baleen plates to capture and filter smaller prey. Although all present-day baleen whales are edentulous obligate filter feeders, the fossil record documents several ...

This paper describes a toothed mysticete that belongs to a basal family found in Oligocene sedimentary rocks deposited in the North Pacific Ocean. The material that is described here belongs in the Chattian stage of the Oligocene, and it was collected ...

Diversity of Pliocene mysticetes from eastern Japan
Island Arc, 1994Abstract Assemblages of Early Pliocene Mysticeti (Cetacea) from the Sendai‐Iwate and Choshi areas in eastern Japan were examined. The early Early Pliocene Tatsunokuchi and Yushima formations of the Sendai‐Iwate area have yielded many cetotheres assigned to Herpetocetus (Cetotheriidae) and some extinct rorquals assigned to Burtinopsis (Balaenopteridae ...

Methods for automatic detection of mysticete calls
The Journal of the Acoustical Society of America, 1994The automatic detection of animal cells has several potential applications: for range, distribution, and, census efforts; for acoustic behavior studies, both local and wide area; for screening of large volumes of data for sounds of interest. Methods were developed for detecting the vocalizations of three species of mysticete: blue, finback, and minke ...

Mysticete whale sounds and human speech
The Journal of the Acoustical Society of America, 1988Toothed whales produce complex sounds, in some cases with two or more simultaneous sources in the head [R. S. Mackay and H. Liaw, Science 212, 676–678 (1981)] but mysticete vocalizations are said to be simple. Frequency analysis of recordings of humpback whales Megaptera novaeangliae on Silver Bank, Dominican Republic, produced sound spectrograms where
