For many decades, invertebrates have been kept as pets, displayed in aquariums and zoos, used for research, and consumed. Maintaining live invertebrates in captivity is becoming more sophisticated and popular as time passes.Arthropod zoos and insectariums,jellyfish exhibits,and captive living coral reefs are relatively commonplace today but were rare or nonexistent 20 years ago. Despite this popularity, diversity, and economic importance, though, veterinary medicine has traditionally paid little attention to this huge chunk (over 95% of the earth’s animal species) of the animal kingdom.
