"How I became an echinoderm scientist" pt. 2 How the experts got their start!

Within the echinoderm research community, there has for many years, existed The Echinoderm Newsletter, a way for echinoderm scientists around the world, to stay in touch and communicate needs and information. The modern online "Echinoderm Newsletter" is here. The Older "Virtual Echinoderm Newsletter" is here.

One of the GREAT parts of this newsletter was a section called "How I became an echinoderm scientist" in which various professional scientists and students wrote short essays on HOW they came to study echinoderms. Some were paleontologists, others were deep-sea biologists, coral-reef ecologists and MANY more. These were interesting accounts-as people who study echinoderms often require...how shall we say, a unique perspective!

Why present these stories? The aspiration of these accounts is not only to provide INSIGHT but also to INSPIRE new generations of echinoderm biologists!

Appropriately enough, today we have FIVE marine biologists (including physiologists, geneticists, taxonomists, and coral ecologists) who have volunteered their stories!

In the 1960’s after the Sputnik surprise there was a great flow of funding into scientific research. I was a naïve student at Hartnell College, a a junior college in central California where two faculty members held NSF research grants. Imagine that today with the teaching load at California’s two-year colleges! I got a part time job working for Howard Feder on his NSF project to identify the chemical substance from starfish which causes an escape response in snails. I couldn’t believe that a person got paid to do this sort of work. To me it was like playing in the laboratory! Howard invited me to work as his technician while he was on sabbatical at the University of Copenhagen Marine Laboratory in Helsingør, Denmark. That laboratory was the home of Gunnar Thorson, the “father of larval ecology”. While there I worked for Howard on feeding responses in the local brittle star that covered the sea floor of the Øresund, the narrow sound that connects the Baltic and the North Seas. When I returned to the US in a few months, it was hard to go back to the junior college. Courses to complete the degree didn’t compare with working in an international marine laboratory; even if it meant feeding clay balls to voracious ophiuroids. I knew I wanted to study marine invertebrates. But I really didn’t realize how influential Thorson was on my thinking.

With graduate school as a goal, I completed the junior college curriculum and went on to San Jose State College. The in 1965, when it was time to choose a graduate school I was looking at UC Santa Cruz and other west coast schools. UCSC was close to San Jose a so I visited there first. There were two faculty members studying invertebrates. (John Pearse didn’t arrive at Santa Cruz until 1971, I think). Ralph Hinegardner had just perfected a laboratory culture technique for sea urchins and he showed me some Lytechinus pictus larvae in his laboratory. I was astonished. How could such a filmy ciliated object become a round dense sea urchin? How does an odd shaped creature like this develop? I knew what I wanted to do. Ideas from larval ecology to developmental biology all seemed so interesting when viewed from the perspective of that minute larva under a stereo-microscope. And even now there is still so much to learn.

When I arrived from France and Senegal in New Caledonia in 1979, I wanted to continue studying fish biology. As in other tropical islands, the fishery in New Caledonia was considered at that time as not important enough to require scientific management. The New Caledonia economy was based on nickel mining and due to the nickel crisis, the authorities wanted to diversify the sources of income and the artisanal fisheries. One of them, the behce-de-mer, was said to have been prosperous once but there was no information! I was asked by ORSTOM (Institute Francias de Recherches pour le Developpement en Cooperation) to undertake studies to determine which holothurian speices were valuable, where they lived, how they grow, reproduce, die, how much could be fished… I started sampling on reef flats and diving in the lagoons with admiration. It was been the start of my association with these wonderful creatures, although mostly depreciated by “non connoisseurs”! I soon met my new echinoderm colleagues at the Seminaire organized in Paris by Alain Guille and we became friends.

I was born and raised in the state of Missouri, in the center of the US. I planned to be a high school teacher in the state. During my studies for the master’s degree at the University of Missouri on the physiological responses of a fresh-water killifish to high concentrations of salt, I became aware that there was much more to the world than Missouri. My oder brother Addison, was also a biology graduate student at Mizzou and had just returned from a summer at Hopkins Marine Station of Stanford Univeristy where he had taken a course in physiological ecology with Prof. Arthur Giese. I had never seen the sea, and it seemed a wonderful thing to do. At this time, Prof. Giese and his laboratory had initiated studies on the reproductive biology and physiology of echinoderms. I had never seen an echinoderm, not even a preserved one. But Prof. Giese accepted me into his laboratory. And I well remember a specific afternoon in September 1960 when I first saw the Pacific Ocean while crossing the pass at Los Gatos in the Coastal Range and later that afternoon when I first saw Strongylocentrotus purpuratus, Pisaster ochraceus, and Patiria miniata in the intertidal at Pacific Grove.

In the sixties and seventies of the last century I worked by snorkel and scuba diving on the interspecific behaviour of fishes (cleanerfishes, feeding associations etc.) in the Mediterranean Sea. Some of those commensal fishes led me to the sea stars on sandy bottoms, especially of the genus Astropecten which they followed in the same way they did with goatfishes, hoping for small invertebrates that were trying to escape. As Astropecten is not an easy genus, I had to learn quite a lot about their way of live and their determination. The more I knew, the more I’ve got interested in echinoderms. When I worked at the Maldives in the eighties, I began to study and to make underwater-photographs of the echinoderm fauna there and found some interesting species. Soon I was able to publish (with help of Loisette Marsh and Frank Rowe) a paper on the seastars of the Maldives. Works on Fromia maldivensis, the seastars of Bali, the colour pattern of Pentaster obtusatus followed. But some echinoderms brought me back to the fishes again, as they are the preferred food resource of some triggerfishes. Feeding associaitons with triggerfishes will be my next task before I’ll come back to seastars of the Philippines.

In 1958, during my last year of a B.Sc. degree at Victoria University in Wellington, New Zealand, three things led me in the direction of the echinoderms. Firstly, for the invertebrates course I was taking, we were required to put together a collection of representative invertebrates from the local rocky shore. On numerous weekend field trips we collected many echinoderms-ubiquitous Patiriella regularis, marauding Pectinura (now Ophiopsammaus) maculata, and squashy Stichopus mollis. They seemed more interesting and exciting than most other animals (with the exception of the beautiful abalone Haliotis iris, which we collected and ate in vast quantities). Secondly, I participated in some of our Zoology Department’s ventures into deep-sea research-we would steam out into Cook Strait in a rented fishing trawler and fish in deep water using long lines, ring nets, try nets, and bottom traps. Bathyal echinoderms, such as Gorgonocephalus or Molpadia, would be collected, and would momentarily distract me from losing my lunch over the side of the vessel. Thirdly, I assisted our echinoderm specialist Prof. H. Barraclough Fell in first-year Zoology Laboratories, and we talked frequently about his favorite subject-echinoderms. As the year wore on, I became very interested in these animals, Barry Fell steered my interest in the direction of the holothurians at that time, probably because he had the other echinoderm groups of the New Zealand region pretty much at his fingertips, and he knew very little about sea cucumbers.

So, for an M.Sc. degree, I studied New Zealand holothurians. Then, for a PhD, I became involved with echinoids as well, from the southern Pacific Ocean and elsewhere. During those years, from 1959 to the end of 1963, I learned much about living and fossil echinoderms from Barry Fell, and collaborated with him on a study of fossil regular echinoids for the Treatise on Invertebrate Paleontology. We exchanged what seemed like a million letters with Treatise editor Ray Moore on a bewildering variety of topics and issues; some of these, for example, the Holothuroidea/ Holothuiodea spelling debate, are unresolved to this day. At that time, 1961-1963, Fell was immersed in his controversial studies on fossil sea stars, and the interrelationships of echinoderm classes, living and fossil. He would meet with Helen Clark Rotman and I, behind closed doors, to reveal his various new ideas. Helen and I seemed to be stunned by it al. Early in 1964 came the Curator of Echinoderms job at the U.S. National Museum, and life has been pentagonal for me ever since.

Pt. 1 "How I became an echinoderm scientist" Geology-University of Illinois Edition!

Today. Something a little different.

Within the echinoderm research community, there has for many years, existed The Echinoderm Newsletter, a way for echinoderm scientists around the world, to stay in touch and communicate needs and information. The modern online "Echinoderm Newsletter" is here. The Older "Virtual Echinoderm Newsletter" is here.

One of the GREAT parts of this newsletter was a section called "How I became an echinoderm scientist" in which various professional scientists and students wrote short essays on HOW they came to study echinoderms. Some were paleontologists, others were deep-sea biologists, coral-reef ecologists and MANY more. These were interesting-as people who study echinoderms often require...how shall we say, a unique perspective!

I have REVIVED the "How I became an echinoderm scientist" feature HERE. And will be reprinting these for everyone to enjoy. Later this week-biologists but today some Echinoderm PALEONTOLOGY!

Why? The aspiration of these is to provide INSIGHT but also to INSPIRE new generations of echinoderm biologists!

TODAY. We start with "How I became an echinoderm scientist"-Three stories from alumni/echinoderm scientists from THE UNIVERSITY OF ILLINOIS AT URBANA-CHAMPAIGN!
How does a Big 10, MIDWESTERN University end up contributing so much to Echinoderm Biology?? Through the long Paleontological legacy at the University of Illinois-GEOLOGY department! Many paleontogists worked on smaller echinoderm stratigraphy type projects during the era when the department's primary expertise was in carbonate (i.e., limestone) and oil geology.

Among them was my advisor...

"
I liked both biology and geology from childhood, and paleontology was a good way to combine the two, and so I majored in geology at the University of Illinois. The midcontinent of North America is a setting of Paleozoic rocks, but for graduate school, I decided to see mountains, oceans, and younger fossils, and so I migrated to the University of California at Berkeley and J. Wyatt Durham’s laboratory. I intended to work on mollusks, but at that time Wyatt was working on Helicoplacus and the echinoid Treatise and I got caught up in all of that. As to asteroids, on my first field trip at Cal, one of the students picked up a fossil “blob," Wyatt looked at it and said “It is a starfish," and something as simple as that started me on the way. (The fossil proved to be an arm fragment of Luidia)."

"My maternal grandfather polished rocks, in retirement. As a teenager, I was fascinated by these attractive stones, which included specimens called “pudding stone”, “petosky stone”, and “alphabet rock”. Alphabet rock was a crinoidal limestone, white crinoid columnals in a dark-colored matrix. Crinoid columnals were cut at all angles yielding the O, C, U, C, B, I, etc. shapes, hence the alphabet rock. This alphabet rock was most intriguing. My grandfather and I did conclude that the “letters” in the alphabet rock were crinoids by consultation with Fenton and Fenton’s The Fossil Book. Although I did not pursue rock or fossil collection or rock polishing as a teenager, I did enter the University of Illinois as an undergraduate major in Geology. At Illinois, Dan Blake was studying fossil asteroids, and two of his graduate students, Dennis Kolata and Frank Ettensohn,
were studying crinoids (and other echinoderms). The seed of interest planted unknowingly by my grandfather took firm root. By the beginning of my junior year, I had decided to study crinoids. I entered graduate school at Indiana University specifically to study fossil crinoids under the direction of Gary Lane. "

"I grew up in SF, a city blessed with museums, aquariums, parks, and easily accessible intertidal and marine habitats. I spent many afternoons digging up insects, looking at fish, and trying to catch planarians and crayfish from the lakes in the park. At the same time, when I wasn't working at family pharmacy-I was at home enjoying Saturday afternoon monster matinees. Weird stuff, science and science fiction fascinated me as a kid. I used to spend hours going through my Dad's first edition of John Buchsbaum's textbook invertebrate text "Animals without Backbones". I was a hardcore volunteer/visitor at the California Academy of Science's Steinhart Aquarium.

I went to Humboldt State University to decide on what I would do with my life and was told that marine biology would probably not be fruitful. But I was stuck on working on invertebrates and nearly decided on a career of either Entomology or Parasitology. I had an internship working at Monterey Bay Aquarium in the Interpretive Programs Office. During the program I was introduced to many species of sea stars (aka starfish or asteroids) that I had never seen before. Pteraster tesselatus! Poraniopsis! Hippasteria! Brisingids!! Strange beasts! Living Monsters! Aliens among us!

My interest continued onto grad school at San Francisco State University and research at the California Academy of Sciences, followed by my PhD at the very distant University of Illinois in Champaign-Illinois, where I got a degree in GEOLOGY of all things! I studied marine animals far away from my ocean!
Since I started my degree I've seen fantastic things from submersibles at the bottom of the Atlantic and Pacific Oceans, from ships in the Antarctic and secrets of starfishes from deep vaults in the museums of Paris. As a student, I could never have believed I would ever be studying starfishes at the Smithsonian. I've had no regrets since....."
