Examination of population genetic structure and movement patterns of beluga whales in Alaska and northwest Canada using nucleotide sequence variation within the mitochondrial genome's control region.
We studied reproductive rate, length of lactation period, pup survival, and mortality of injured and uninjured female Hawaiian monk seals on Laysan Island, northwestern Hawaiian Islands, in 1983 – 1989.
The pelage of the adult seal is composed of clearly defined bundles, each with a coarse guard hair and 35 to 40 fine underfur hairs; there are more than 300,000 fibers to the square inch.
