theweaselkingSquid overtake humans as dominant species on the planet.
According to scientists, squid have overtaken humans in terms of total bio-mass. That means they take up more space on the planet than us. The reason has been put down to overfishing of other species and climate change.
A report in the Australian science journal, Australasian Science, said marine researchers are now in universal agreement that cephalopods have been given an advantage not available to any other sea creature.
Overfishing of some fish species has taken away competition for the squid in finding food resources. The warming of waters due to climate change have also allowed squid to expand their populations.
Dr George Jackson from the Institute of Antarctic and Southern Ocean studies in Tasmania said squid thrived during environmental disasters such as global warming. The animal ate anything in that came their way, bred whenever possible and kept growing.
"This trend has been suggested to be due both to the removal of cephalopod predators such as toothed whales and tuna and an increase of cephalopods due to removal of finfish competitors,'' said Dr Jackson.
