Jellyfish Central

Jellyfish Central is my ongoing collection of articles, research and thoughts on  jellyfish and invertebrate.

Jellyfish captured my attention and imagination in the mid-1980s, about midway through my fifty-year career in vision research. At the time I was chief of the Laboratory of Molecular and Developmental BiologyNational Eye Institute, National Institutes of Health (NIH) in Bethesda, Maryland. My specialty was gene expression in the eyes of vertebrates.

While reading a new book on invertebrate vision, I learned that complex jellyfish eye looked like a variation of the highly evolved human eye!

It appeared to me that Jellyfish eyes seemed much more than evolutionary stepping-stones to vertebrate eyes; they were small jewels.

I suddenly, impulsively, wanted to study jellyfish eyes. Stepping into the strange universe of jellyfish resonated with the excitement I had in choosing a career in biology many years earlier. But where to start?…

Ricardo, the protagonist in my novel Jellyfish Have Eyes speculated that jellyfish are smarter than we think, that they have a brain of sorts, and that they interact in jellyfish lingo that we don’t understand - gibberish talk. Jellyfish may be a bit extreme, but I think Ricardo makes his point: don’t be too sure that [...]

"Relevance is a malleable term." I had dinner last night with Sophia Lass; bless her sweet nature. Ricardo was lucky to have her as his lawyer in my novel Jellyfish Have Eyes. She begged me not to steal her thunder by divulging the outcome of her efforts. Fair enough. What a ravenous appetite she had, [...]
