(16) As air breathers that are inseparably tied to the surface, cetaceans are highly trackable; they may thus help in the monitoring of habitat degradation and other long-term ecologic change.

(18) We sequenced the mitochondrial DNA D-loop regions from two cetacean species and compared these with the published D-loop sequences of several other mammalian species, including one other cetacean.
(19) The predominant cell of cetacean epidermis, not found in normal terrestrial mammals, is a lipokeratinocyte, which elaborates not only keratin filaments, but also two types of lipid organelles: first, lamellar bodies, morphologically identical to those of terrestrial mammals, are elaborated in great abundance in all suprabasal epidermal layers, forming intercellular lipid bilayers in the stratum corneum interstices: and second, non-membrane-bounded droplets appear and persist in all epidermal layers.
(20) I do not believe that scientific studies of whales (or any cetacean species) must be lethal in order to be effective for management and conservation of the species.
Narwhal
Definition:
(n.) An arctic cetacean (Monodon monocerous), about twenty feet long. The male usually has one long, twisted, pointed canine tooth, or tusk projecting forward from the upper jaw like a horn, whence it is called also sea unicorn, unicorn fish, and unicorn whale. Sometimes two horns are developed, side by side.
Example Sentences:
(1) Documents seen by the Guardian show that Mittal's company, the world's biggest steel-making group, ArcelorMittal , admits the operations will be undertaken in an area inhabited by unique wildlife including polar bear, narwhal and walrus.
(2) The evolution of the component was studied after sequencing the component in different odontocetes representing the Delphinidae (delphinids), Monodontidae (narwhals), and Ziphiidae (beaked whales).
(3) As sea ice melts, the bowhead whale and the narwhal will lose protective cover, while other species such as the ringed seal will struggle to breed.
(4) "Ned was stalking me, baiting me, hunting me, much as he was the demon narwhal, albeit with more subtlety than force.
(5) Values for Young's modulus of elasticity, ultimate and yield stresses, ultimate and yield strains, work under the stress-strain curve and work of fracture were obtained from tensile and bending tests on specimens of narwhal tusk dentine and cement, femoral bone from young and mature cattle, and reindeer antler.
(6) In general, the mechanical properties of the narwhal tusk tissues were as would be expected from their mineral content, except that the stiffness of the cementum was low.
