Baleen Whales have two blow-holes on the top of their heads whereas Toothed Whales only have one. Estimated length ofprey was determined from measurements of otoliths and beaks recovered in the tank and relationships of otolith and beak measurements to prey length. Toothed whales are grouped together in Odontoceti, which includes oceanic dolphins, sperm whales, pygmy and dwarf sperm whales, porpoises, beaked whales, beluga whales and narwhals, and river dolphins. Depending on species, they eat a variety small crustaceans, squids, and small schooling fishes.Fin whales eat krill, copepods, squids, and variety of small schooling fishes.Humpback whales, Bryde's whales, and minke whales prey mostly on krill and small schooling fishes. Without this knowledge, it becomes difficult to assess the effects of anthropogenic sound, since there is no way to determine whether the disturbance is impacting the species' physical or environmental requirements. Our findings also suggest that there is a considerable difference between the diet of short- and long-finned pilot whales (Globicephala melas) in the western North Atlantic. Paper SC/40/SM20 submitted to the Scientific Committee of the International Whaling Commission.Goodall, R. N. P., Folger. We calculated relative prey size frequency spectra for 13 species of toothed whale from the northeast Atlantic.

Beddington. Variation in the position and shape of these tusks was examined in four sympatric species and was found to be consistent with the hypothesis that these differences may have evolved to aid species recognition between sympatric and otherwise morphologically similar species of this genus.Thesis (Ph.D.)--University of Aberdeen, 2005. Paper SC1 Todaropsis eblanae and Todarodes angolensis were indicator species for the upper slope benthic, from 300 to 500 m, but on the lower slope, in 700–900 m of water, they were replaced by Histioteuthis miranda and Opisthoteuthis agassizii. Strap-toothed Whales feed nearly entirely on oceanic squids.Nesis, K. N. (1987). A. The bubbles float up in a column, keeping prey inside the column. 1994;... Its distinctive colour pattern and the visible tusks of adult males also make the species fairly easy to identify at sea (Jefferson et al., 2008). The families Gonatidae and Cranchiidae were the predominant cephalopod prey, accounting for 86.7% of the diet. Largest and Smallest Whales. IDCR Southern Hemisphere Minke Whale Assessment Cruises, 1978179-1987188. It seems that the microbial flora can adapt to different preys. in the skeletal muscle, and lung lesions related to parasitic damage and pneumonia or chronic infection. Ginkgo-toothed Beaked Whales occur over a broad latitudinal range in the deep waters of the tropical Pacific and Indian Oceans. When examining all odontocetes, there were only weak correlations between skull shape and prey size. Der Magen der Cetaceen ist bei allen Spezies mehrkammerig und wurde wiederholt mit dem Wiederkäuer-Magen verglichen. Nothing is known about the diet of this species. This cetacean is probably the least known whale on the planet.
Living in temperate waters, the Spade-toothed whales may be threatened by climate change, causing ocean warming, which in turn leads to reduction and modification of their natural range.According to the IUCN Red List, the total population size of the Spade-toothed whales is unknown for today. A. Cranchia scabra indicated the presence of oceanic water at stations 700–900 m deep. The myctophid Symbolophorus evermanni was a substantial prey item for both species. Krill (a family of small, shrimplike crustaceans) and copepods are major components of a right whale's diet.Rorquals generally eat larger prey than do right whales. The gastrointestinal tract of pinnipeds is most likely equates to that of other carnivores. Pilot whales tend to gather in large pods and may mass strand.Long-finned pilot whales are found in the Atlantic, Pacific, and Indian Oceans, plus the Mediterranean and Black Seas. Some whales, such as the Sperm Whale, can stay underwater for up to two hours holding a single breath. Unlike baleen whales, toothed whales have teeth that they use for catching prey and also have a single rather than a double blowhole. This stranding occurred more than 5000 km from the normal distribution of the species in cold temperate waters below 35°S. Paper SC/40/SM20 submitted to the Scientific
