(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.
Mammal
Definition:
(n.) One of the Mammalia.
Example Sentences:
(1) The high amino acid levels in the cells suggest that these cells act as inter-organ transporters and reservoirs of amino acids, they have a different role in their handling and metabolism from those of mammals.
(2) Ernst Reissner studied the formation of the inner ear initially using the embryos of fowls, then the embryos of mammals, mainly cows and pigs, and to a less extent the embryos of man.
