Jay Hemdal has kept aquarium fish since he was four. He set up his first marine aquarium in 1968 when he was nine years old. He later worked part time for many years at various local retail pet stores and fish wholesale companies while he was living at home and then during college. After graduating from college with a degree in aquatic biology, he managed the aquarium department of a large retail pet store for five years until 1985, when he was hired as an aquarist/diver (and later department manager) for the John G. Shedd Aquarium in Chicago. In 1989, he accepted the position of curator of fishes and invertebrates for the Toledo Zoo and Aquarium. The historic Aquarium at the Toledo Zoo underwent a renovation and reopened as a completely new, $25.5 million facility in the spring of 2015. Jay has written over 200 articles and papers as well as seven books since 1981. Jay is currently the Toledo Zoo’s General Curator and has been since 2017.
