Pelagic


Definition:

  • (20) In addition to acting as a chemosignal, the Harderian material serves two major homeostatic functions: (1) the lipids on the pelage act to insulate the animal against cold and wetness, and (2) the lipids and pigments darken the pelage and increase radiant absorption.

Shearwater


Definition:

  • (n.) Any one of numerous species of long-winged oceanic birds of the genus Puffinus and related genera. They are allied to the petrels, but are larger. The Manx shearwater (P. Anglorum), the dusky shearwater (P. obscurus), and the greater shearwater (P. major), are well-known species of the North Atlantic. See Hagdon.

Example Sentences:
