| Abstract | Plastic embryological models lack the excitement of seeing real, live embryos. Chick embryos are often used to demonstrate embryological development and blood circulation to students but this necessitates the death of the organism. "Kryptolebias marmoratus" embryos are large and can be viewed by means of a light microscope without need to harm the organism. Eggs are easily obtained from captive fish; and are easy to display to students. Embryological features common to early human development are readily visible in the "K. marmoratus" embryos: early brain development, eye development, somites, limb buds, blood circulation and pigment cell migration. Embryos also twitch when exposed to light and the beating heart is readily viewable. Use of the embryos in a class room has proven rewarding, students marvel at observing embryological development and are more eager to consider the common embryology and evolution of chordates.
