<Anchor> In the

offshore of Jeju, a mother dolphin was caught trying to survive as she was unable to let go of a dead baby and pushed it up to the surface.

It seems that he has been doing the same for over two weeks, but reporter Ki-hyung KNN reports.

<Reporter> A

group of dolphins appeared off the coast of Jeju Island. Southern Great Dolphin. There are over 30 even when I guess.

Something white is hanging on one's back. I went closer. Dead young dolphin.

The mother keeps pushing over the water to save the baby.

The mammalian dolphin must rise to the surface to breathe.

The body is already rotten, but the mother does not give up.

[Kim Hyun-Woo/National Fisheries Research and Development Institute, Whale Research Center: The mother was repeatedly acting to save the young without recognizing the baby's death. Given the same case in foreign countries, it is very likely to be a mother.] A

mother who is unaware of death appears to have repeated the same behavior for more than two weeks.

In 2008, a group of dolphins on the East Coast were caught pushing their dying colleagues into a group.

Some experts believe that this is a funeral act for a dead cub or colleague.
