A bizarre footage has emerged of a goldfish that is swimming for around three days despite its head bitten off by a predator.
Lin Shaolun, from Taiwan, said the green-tinged goldfish was fed to a puffer fish, but managed to survive the ordeal.
The fish lost its entire head, but the eerie footage shows it swimming around the bowl as normal, The Sun reported.
Some viewers suggested the fish had only lost its gills and jaw and was able to keep moving as its brain was in tact.
Others appeared concerned for the other fish in the tank.
“The wound can potentially lead to bacterial infection and it could contaminate the water,” one person wrote.
The owner said the goldfish managed to survive for three days.
