Marine mammal used in pioneering research back in limelight

WAIMANALO, Hawaii (AP) — Compared with other marine mammals, 40-year-old Kina has lived a particularly winding and high-profile life.

She went from the open ocean off Japan, to a Hong Kong amusement park, to a classified U.S. Navy program, to a Hawaii research lab. Along the way, studies using the false killer whale — a dark-gray member of the dolphin family with a big, round beak — led to major discoveries on whale hearing and aided in the development of modern military sonar .

“The work that (researchers) have done over the years is quite valuable, and certainly groundbreaking,” said Robin Baird, a marine biologist with the nonprofit Cascadia Research Collective, a scientific and education group based in Olympia, Washington.

Now, Kina is again making waves, this time with her latest move to an Oahu marine park. Animal-rights activists say the 13-foot-long (4-meter), toothy mammal and her captive companions deserve peaceful retirements but are instead being traumatized as tourist attractions confined to concrete tanks.

But Kina’s handlers maintain she is in excellent care, receiving the best food, veterinary attention and stimulating training, all while continuing to contribute to important science. And park officials say she won’t take part in any acrobatic shows like other dolphins in their care.

Kina’s journey started in the wild over 30 years ago, when she was captured during a Japanese dolphin hunt. She is believed to be the last living animal in the U.S. from that now-widely condemned fishery. The fishermen sold her to a Hong Kong amusement park, where the U.S. Navy acquired her in 1987.

For the next six years, the Navy used Kina for classified research on sonar, the use of sound to communicate, maneuver and detect objects underwater. It kept her at a Marine base on Oahu’s Kaneohe Bay, the largest sheltered body of water in the main Hawaiian Islands.

When that program ended, Kina went to a University of Hawaii lab on Coconut Island, also in Kaneohe Bay, where her science career continued for over 20 years. She took part in echolocation studies that could someday lessen the impacts of man-made ocean noise on marine wildlife. Cetaceans — dolphins, whales and porpoises — use sound waves and echoes to hunt and navigate.

But the university was spending nearly $1 million a year to care for Kina in an ocean pen. So in 2015, amid…
