Following our story of Overweight Monkeys, now the dolphins at Kinosaki Marine World are also having weight problems.

Zookeepers were wondering why the dolphins were having trouble making high jumps during shows, so they measured their weight and found all had gotten plumper.

Some of the dolphins had gotten up to 22 pounds heavier just during the summer.

The main reasons was because the mackerels on their menu had unknowingly gotten fattier this year. Which is why even though the menu was the same, the dolphins were consuming more calories than usual.

Now the dolphins have to undergo a diet too. LOL

How come Japanese people are so skinny and yet the animals in their zoo are all getting fatter. LOL
