In other words, scientists have found that the smaller the organism, the more such individuals live in the ocean. For example, crustaceans are a billion times smaller than tuna, but they are also a billion times larger. Scientists have suggested that this rule could apply to all living organisms in the ocean, from the smallest bacteria to the largest whales. This assumption was confirmed.
But now it seems that humans have violated this fundamental law of the ocean. In a November article for Science Advances, the researchers said the rule is no longer true for larger sea creatures. Due to industrial fishing, the abundance of large fish and marine mammals in the ocean has become much lower than it should have been.
