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?…

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 [...]

Sex, Survival and Immortality: Jellyfish Are Our Superiors

We humans are so smug. We consider lowly invertebrates primitive. We think we’re smart and can outlast hard times better than animals can in the wild by using our wits and engineering skills, which I admit are impressive. We figured out how to outdo Nature and switch our sex to become what we call [...]

The gallery in this post features strong pieces of art, masterfully done, that make the case that jellyfish proliferation affects all of us and has filtered to art, as important issues always do.

Jellyfish Invasion!

By |2021-02-27T08:53:06-05:00January 29th, 2016|Categories: Blog, Jellyfish Central|Tags: |0 Comments

Half a billion years ago, before what is known as the Cambrian explosion when myriads of new species sprouted in the oceans, jellyfish roamed the seas. Jellyfish adapted to sharing their environment with other animals and continued to thrive for hundreds of million years, and they are with us now. But things are changing for [...]

Why Jellyfish?

Editor’s note: Fusing memoir and fiction, Joram’s own research fuels the adventures of his protagonist Ricardo Stein in Jellyfish Have Eyes. As an NIH scientist acclaimed for vision research, he had 20 years of dissecting the eyes of vertebrates under his belt when he learned that, indeed, jellyfish have eyes. Which leads me to this [...]

A Letter to Lillian

By |2017-07-23T21:09:31-04:00January 4th, 2016|Categories: Jellyfish Have Eyes!, Ricardo Sztein|Tags: , , , |0 Comments

Many years after Dr. Ricardo Sztein had passed away, the following letter was found tucked away through a rip in the underbelly of the mattress of his room. We don’t know when he wrote the letter since it wasn’t dated. Poor Ricardo, a good man, tormented, who craved to be understood. Dear Lillian,             How [...]
