Uncinaria spp. were recovered from the milk of California sea lions ( Zalophus californianus) collected from the: (1) teats of a cow just after parturition (one parasitic third-stage larva, L(3)), (2) stomach of her nursing pup (two L(3)), and (3) stomach of a dead pup about 2 days old (one L(3), one headless, probably L(3), and four L(4)) on San Miguel Island, California in May 2001. This, in addition to earlier research, indicates transmammary transmission of hookworms in this host. Uncinaria spp. were found in dead northern fur seals ( Callorhinus ursinus) in the: (1) intestines of 2 of 75 pups (either one or two adult specimens in each infected pup) and (2) ventral abdominal blubber of 3 of 78 subadult males (one to seven L(3) in each infected seal) on St. Paul Island (SPI), Alaska in July and August 2001. These findings verify the low current prevalence of Uncinariaspp. in fur seals on SPI. Rectal fecal samples taken from 50 live Steller sea lion ( Eumetopias jubatus) pups, about 1 month old, on Rogue Reef in Curry County, Oregon in July 2001, were all negative for the eggs of Uncinaria spp. The apparent zero infection rate in these pups is possibly because the rocky terrain of this rookery is not suitable for hookworm transmission.
