Enneacanthus chaetodon
The Black-banded sunfish (''Enneacanthus chaetodon'') is a freshwater fish species of the sunfish family (Centrarchidae). They are found in the United States ranging from New Jersey to central Florida. The defining feature of this Black-banded sunfish is the black vertical strips that it has on both sides of its body. The term "Enneacanthus" comes from the Greek terms ''ennea'', which means "nine times", and ''acanthi'', which means "thorn".〔(Enneacanthus chaetodon Blackbanded sunfish )〕 It is in a genus that consists of only three species along with the Banded Sunfish ''Enneacanthus obesus'' and the Blue-spotted Sunfish ''Enneacanthus gloriosus''. Collectively, they are commonly referred to as the "Banded Sunfish" or "Little Sunfish".〔(Animal-World Pet and Animal Information )〕
== Description ==
The Black-banded sunfish is fairly small, maximum length of 10 cm, with an average life span of 3–4 years. The average length of this sunfish is around 6 centimeters in length. The Black-banded sunfish has a very compressed, deep body with a small mouth but big lower jaw extending upwards.〔 Its gill cover has a black spot, and the dorsal (top), anal (back/bottom), and caudal (tail) fins are black-mottled. Its dorsal fin stands upright with 10 spines and the tail fin is somewhat rounded. The body coloration is mostly a shiny silver with yellow spots.〔(Blackbanded sunfish (Enneacanthus chaetodon) )〕 The Black-banded sunfish gets its name from the six black vertical lines on each side, starting with the first line running through its eye and five more vertical lines back to the tail fin.〔(Diszhal )〕
