TOKYO — Dolphins at a Japanese marine park are going on a low-fat diet after developing pot bellies and failing to look sharp in their aquatic performances.
Kinosaki Marine World said Tuesday that all of its 19 dolphins have been on a diet since late August, when they started failing to hit jumping targets and keep upright while treading water.
Keepers found all had gained weight, some up to 22 pounds, just during the summer.
All had the same menu — about 31 pounds of mackerel mixed with some whitefish — but keepers found the mackerel had gotten fattier, adding too many calories for the dolphins. The Associated Press
