Jellyfish Have Eyes!

Yes, jellyfish have eyes. In fact, the complex jellyfish eye looks like a variation of the highly evolved human eye!

Some twenty-five years ago in the mid-1980s, midway through my fifty-year career in vision research, I learned that jellyfish have eyes. At the time I was chief of the Laboratory of Molecular and Developmental BiologyNational Eye Institute, National Institutes of Health (NIH) in Bethesda, Maryland.

As I ploughed through a book on invertebrate vision on reading, suddenly a life-changing moment arrived: a chapter on eyes of Cnidarians, the invertebrates that include corals, sea anemones and jellyfish.

Most cnidarians are plant-like animals stuck to the ground and don’t have eyes. But jellyfish are a different story.  I was amazed to learn that the cubomedusan jellyfish (known as box jellyfish due to their symmetrical shape) have sophisticated eyes. What most people consider slimy globs that sting if you touch them (the painful sting of the notorious Australian box jelly can be lethal) are actually animals that can see!

Kirkus Reviews: An intelligent, wistful rumination …

Cover of Kirkus Reviews Feb 2019. Jellyfish Have Eyes is featured in this edition

Piatigorsky (The Speed of Dark, 2018, etc.) offers a speculative novel about a researcher undertaking a pure-knowledge scientific study in an era of hostility to free inquiry.

Financial collapse in the near future has left the United States with a huge unemployment rate, new diseases appearing and old scourges returning, more conservatives in Congress, and a rabble-rousing Washington, D.C., reporter slamming taxpayer spending on any research that doesn’t promise immediate, practical payoff. In the 2040s, researcher Ricardo Sztein is an aged, respected fixture at the Vision Science Center who is shaken after his wife’s cancer death. He embraces his other great love—science experimentation just for the sake of knowledge, not a dictated agenda or financial return. His curiosity about how jellyfish see with multiple eyes (“rhopalia”) of unexpected complexity sends him to the swamps of Puerto Rico, supported by like-minded colleagues and a loan of NASA computer tech. Clues uncovered in his field lab hint at new revelations about animal perception and evolutionary biology. But when his rambles become publicly known, grandstanding politicians and media condemn him, cuing a public tribunal that’s reminiscent of that in the film Inherit the Wind. Piatigorsky is a scientist and essayist, so he knows of what he speaks regarding the cloistered realm of modern inquiry and exploration, which includes people jockeying for grants with ambition masked by professional etiquette. He also expresses scientists’ angst that average citizens appreciate nothing about basic research and could pull the plug on it at any moment. The future that the author evokes in this high-minded, speculative drama is thinly sketched, but what readers do glean about it is unpleasant, indeed. The jellyfish material, meanwhile, seems fanciful, but it’s firmly based in fact; the author includes photographic illustrations here that shore up the science. Still, it’s an intelligent, wistful rumination on the value of scientific pursuit, the joy of discovery, and the loneliness of a maverick thinker. A sensitive drama about an aged scientist in an anti-intellectual era.

In the prologue of my novel Jellyfish Have Eyes, Ricardo reflects on his dead wife and tells her, “If you had been there and seen the jellyfish, Lillian. They have eyes and minds. We have so much to learn from them.” Ricardo, a fierce believer in chasing ideas that fascinated him, had gone to La [...]

Jellyfish Survival Tricks

Scientific observations suggest that Aurelia aurita, a moon jellyfish, can age backwards. The ability to regenerate missing parts is not only an invaluable survival strategy in biology, it’s also potentially of great medical importance. Observations by Jinru He, a graduate student at China’s Xiamen University, suggest that Aurelia aurita, a moon jellyfish, goes a [...]

Facing Lethal Jellyfish

Would you venture in anyway? Would I face a lethal jellyfish - with eyes? Scrolling through recent jellyfish news I came across some interesting articles. Beware these so-called “blobs.” One article was from West Australia about large numbers of box jellies washed up on the beach.  I have occasionally seen various species of jellyfish on [...]
