A classic example of a population bottleneck is that of the northern elephant seal, whose population fell to about 30 in the 1890s. Although it now ...
The ultimate goal is for every animal rescued by TMMC to be released back to the ocean with a second chance at life. Since 1975, the center has rescued over 24,000 marine mammals, [2] mostly California sea lions, northern elephant seals and Pacific harbor seals. The center can have upwards of 275 animals at the hospital at one time.
