So often we talk about a fish species. But what is a species. What defines it, why they sometimes are changed after years of study and other questions will be answered.
Our speaker is Eric Thomas and here is the story:
When is a Species Not a Species?
An explanation of how new species are named and described scientifically, and coverage of various informal hobby naming systems (including L-, C-, D- and A- numbers) for organizing
undescribed species.
Eric Thomas, Ph.D. is an associate professor of Biology, co-chair, and director of graduate studies for the Biological Sciences Department at the University of the Pacific in Stockton, California. With a lifelong passion for fishkeeping, Eric has maintained and bred various species since childhood, specializing in catfish, particularly Corydoras, Loricariids, Auchenipterids, and Microglanis.
His research focuses on reproductive pheromone production in Hymenochirus frogs and self-poisoning mechanisms in Corydoras catfish, with recent studies on Microglanis bumblebee catfish in Peru. He operates up to 27 aquariums and keeps over 40 species.
Beyond academia, Eric shares his expertise through his YouTube channel Bekateen, Facebook page Bekateen’s FishRoom, and as a moderator on PlanetCatfish.com. He also serves as the program coordinator for the Sacramento Aquarium Society.
