Australian biologists have studied the historical data on catches of cephalopods in the period from 1953 to 2013 and found that the squid, octopus and cuttlefish quantity in the ocean is getting bigger and bigger.

The research results have surprised the scientists, because the fish and coral populations, by contrast, were reduced due to the negative human impact and climate change. Perhaps the rapid multiplication of cephalopods is related to the fact that intensive fishing has reduced the number of predators and competitors. According to another version, octopuses and their colleagues better adapt to the changes in their habitat due to the exceptional fertility, short lifespan and promiscuity in food.
