Scientists in Australian spotted and identified a fish which can walk and breathe out of water for at least six days. They warn that the fish can cause a massive imbalance in the ecosystem.

James Cook University scientists discovered that this fish, which comes from “nearby” Papua New Guinea, can kill birds and bigger fish by crushing their necks.

Even though not many of the species have been spotted, it is estimated that if many of them exist in the same ecosystem they can upset the eco-balance.
