Raymond Gibson (1938–2023): in memoriam

On 29 January 2023, Raymond (Ray) Gibson (Fig. 1), Professor Emeritus of Liverpool John Moores University, died in a hospital on the Wirral. He lived a very busy life, rich in travels and scientific discoveries, and he was one of the most authoritative world experts in the taxonomy of nemerteans. Ray was born on 23 November 1938 in Catterick Village in Yorkshire. He gained his Private Pilot’s License aged 17 and had several adventures in the small plane. In 1965 after leaving the Royal Airforce as a qualified pilot he got his B.Sc. in Zoology First class degree from Leeds University and in 1968 gained his Ph.D. from Leeds University. Ray began his interest in nemerteans when he was a student at Leeds University. His Ph.D. supervisor was Dr. Joe Jennings, who at the time was researching the nutrition and digestion of nemerteans and “turbellarians” (a grade of free-living platyhelminths). Ray’s first articles on the nutrition and biology of Malacobdella grossa were published when he was at Leeds University (Gibson 1967, 1968; Gibson & Jennings 1969). In 1971 Ray joined the Liverpool Regional College of Technology (this became Liverpool Polytechnic and then Liverpool John Moores University), where he worked for 30 years. His first book (Gibson 1972) is an excellent summary of knowledge on nemertean biology at the time and has ‘entangled’ (rather than ‘hooked’) young students worldwide in the following generations into this field. Ray’s exploratory enthusiasm was unmatched. He would come early in the morning and spend the day in concentrated writing, microscopy, or figure preparation. An ashtray was ever present next to his microscope and cigarettes and black coffee were all he needed to sustain him through the long days. For a long time, the histology unit was complete with the all-pervasive smell of xylene. He supervised post-graduates from many countries and backgrounds, teaching them the intricacies of paraffin sectioning and histochemistry.Peer reviewe

Aquatic Nuisance Species: An Investigation of a Biological Control Agent for the Green Crab

Since their first sighting in the San Francisco Bay in 1989, European green crabs (Carcinus maenas) have undergone what can truly be called a population explosion. In 11 years, they have spread south to Morro Bay and north to British Columbia, Canada. Untold millions now live under rocks in mud-bottomed areas of the state’s estuaries. Although they have not yet become established on the outer shoreline--perhaps because they cannot tolerate heavy wave action--some biologists believe it is just a matter of time before they spread to the coast
