The Zebrafish poster portrays the critical embryonic stages and the details of adult anatomy, including aspects of sexual dimorphism. Internal organs are illustrated in multiple dissections: heart, gut, liver, spleen, pancreas, ovaries, testes, swim bladder, and kidneys. A midsaggital section shows a male and a female stained in a histological prep. Additional illustrations highlight the brain, skeleton, gills, and gill arches. This poster is illustrated by Gheorghe M. Constantinescu, DVM, PhD, Drhc, the veterinary anatomist and medical illustrator at the University of Missouri-Columbia.
