At Ano Nuevo, the researchers move through the seals like border collies moving through a ___of sheep, gradually zeroing in on a 500-pound female, which by the standards of elephant seals is ___anorexic.
Jason Hassrick moves in quickly and ___ a load of sedatives into the rear end of the female. Two minutes later, she’s out like a light, although her eyes ___ wide open. So far, so good says Hassrick, who works in Dan Costa’s lab.
