Viral Dolphin Video Sparks Debate on Animal Mourning Behavior

A mother dolphin named Fraggle was filmed swimming with her baby who had died.

The video was shared on July 20 by a whale conservation group.

Fraggle's calf was only two weeks old.

Experts think the calf probably died from pneumonia.

Fraggle had already lost three other babies before this one.

Scientists say mother dolphins often carry their dead babies for many days.

They believe this is how dolphins show sadness, just like people grieve.

In the video, other dolphins stayed close to Fraggle instead of swimming away.

Similar sad behavior has been seen in other whales, like an orca named Tahlequah, and even in monkeys.

Researchers say there is still a lot to learn about animal feelings.
