Nomura’s jellyfish, a species frequently encountered in Japan and China, is one of the largest in the world. The body can reach a diameter of 2 m. Since they create big problems for the fishing industry, Japan has now sought China’s help on the issue. It is thought that a recent proliferation of the species, huge swarms appearing every year since 2000, originates at the mouth of the Yangtze river.

Evolution can do fascinating things sometimes. Upon reading about this, a doubtlessly romantic and delusional notion entered my mind. What if the sea ecosystem, or a subset of it, say 10-100 species, perceive the human fishing industry as a threat that needs to be defended against, and in response create an evolutionary niche where a new kind of species can thrive, a species whose only purpose is to obstruct fishing? A romantic notion since it plays off the mythical idea that human beings are at war with nature, or that nature is good and man is evil, something I don’t really believe in. But an interesting one nonetheless. Is such a development possible?
