Veterinarians are preparing rare emergency efforts to administer antibiotics to a young emaciated orca that's part of an endangered pod and whose survival is uncertain.
Teri Rowles with NOAA Fisheries told reporters Tuesday that veterinarians will do a health assessment when the 3½-year-old female killer whale shows up again in Washington state waters.
They'll decide then whether to administer antibiotics using a dart injector or a long pole syringe.
They would decide after that whether to feed the orca live salmon from a boat, which has never been attempted in the wild.
The animal, which was last seen Friday, is part of a population of critically endangered orcas that's dwindled to just 75 whales.
Another female orca from the group attracted global attention as she tried to keep her dead baby afloat.
