Lethal entanglement in baleen whales.
Understanding the scenarios whereby fishing gear entanglement of large whales induces mortality is important for the development of mitigation strategies. Here we present a series of 21 cases involving 4 species of baleen whales in the NW Atlantic, describing the available sighting history, necropsy observations, and subsequent data analyses that enabled the compilation of the manners in which ...
متن کاملThermoregulation in feeding baleen whales: Morphological and physiological evidence
Gray whales (Eschrichtius robutus) expose their immense oral cavities repeatedly to frigid waters when feeding. Morphological structures for heat conservation in the tongues of gray whales are described here in detail. Numerous individual countercurrent heat exchangers converge at the base of the tongue to form a bilateral pair of vascular bundles called the lingual rete. Temperature measuremen...
متن کاملDecoupling Tooth Loss from the Evolution of Baleen in Whales
Baleen whales, or mysticetes, include the largest vertebrates to have ever evolved. Their gigantism, evolutionary success, and ecological diversity have been linked to filter feeding. Mysticetes filter feed using elaborate keratinous baleen plates, which grow from the palate and allow them to strain large quantities of prey out of the water. While the earliest mysticetes retained the adult, min...
متن کاملEnvironmental Influences on Diel Calling Behavior in Baleen Whales
Baleen whales rely on acoustic communication to maintain contact with conspecifics for the purposes of social interactions, breeding, and possibly coordinated feeding activities. Passive acoustic monitoring takes advantage of this communication to detect whale presence. Unlike odontocetes that use echolocation to forage, calling in baleen whales is by no means obligatory; therefore, the absence...
