Goatfish

The Goatfish is a perciform fish and can be found worldwide in tropical, subtropical and temperate waters. They are characterized by a streamlined body with two dorsal fins, a forked tail and a pair of sensory barbels under their chin which help them find food that is hidden in the sand, locating the prey both by touch and taste.
An interesting fact is that the goatfish has the ability to rapidly change its color in order to blend in with its surroundings and to become less visible to predators. Evenmore, two species of goatfish have learned how to mimic the blue-striped snapper with whom they often form schools.
In Ancient Rome they were highly sought-after and expensive and used for guest appreciation, due to their unique colors and shades. The fish was served alive in order for it to die right before the eyes of the guests so they could observed it.
