The red leech monster swallowed up the big worm in the blink of an eye

BBC has just published a documentary that scared many people. The main character in the video is a red leech up to 1m at Borneo Island, Indonesia.

>>>Leech can become a problem like yellow snail

This giant leech can swallow a large earthworm. Filmmakers discovered leeches on Mount Kinabalu, the largest mountain on Borneo.

This leech species has just been discovered and it still has no official scientific name. Members of a tribe at Mount Kinabalu call it "giant red leech".

Giant red leech is one of the largest leeches in the world. Scientists believe that large individuals of this leech species may even be longer than 1m.

In the documentary, the leech has sniffed the earthworm from quite a distance. When meeting the prey it moves very fast and rushes to swallow its prey.

The director of the documentary, Paul Williams, said the leech swallowed the prey like the python did.

The title has been changed.
