After years of pressure to set the Miami Seaquarium orca free, Lolita was scheduled to spend her final days in her natural habitat sometime next year. On Friday, she died of a "renal condition."
The marine mammals have been "attacking" sailboats since 2020. But those encounters are becoming more frequent, and some say the orcas' tactics are evolving.
Orca moms spent precious resources feeding their fully grown adult male offspring. A new study finds that this may limit how many more young they produce.
A killer whale more than 20 feet long died after beaching itself in Palm Coast, Fla. This is the third known orca to be stranded in the southeastern U.S. and the first since 1956, an official says.
In recent years, orcas have been damaging the rudders of pleasure yachts, mostly along the coasts of Portugal and Spain. Scientists and sailors are struggling to understand the encounters.
Lolita was captured five decades ago in the Puget Sound. Animal rights activists say she's the oldest orca in captivity and should live her final years back home in a seaside sanctuary.
Washington's orcas are hungry, because there aren't enough salmon for them to eat. State officials want to take out some dams to help them, but that would hurt Washington's wheat farmers.
What began as a moment of joy ended in tragedy when the infant died last week. Since then its mother has refused to let go, holding her child tightly in what experts call a moving expression of grief.
The calf was the first to be born in the endangered pod of Pacific Northwest killer whales in three years.
Historical photos show fishermen with chinooks almost as tall as they are. A century's worth of dam-building, overfishing, habitat loss and hatcheries has cut the size of the average fish in half.
