| The Yellow Tang is mostly herbivorous, meaning it eats autotrophic organisms,
but it also eats heterotrophs. It prefers to eat algae or other
plant-based foods; however, it does eat small invertebrates like
brine shrimp. The Yellow Tang uses its long snout to reach into small
crevices to get hidden algae as well as using it to pull
seaweed and grasses apart. (See Adaptations)
Yellow Tangs have a complete digestive tract.
Nutrition and oxygen are pumped through a one circuit circulatory
system, by a two chambered heart.
