Generally, they exhibit a base color ranging from olive green to golden yellow, often with three prominent vertical bars or blotches along the flanks. Many species also display iridescent spots or vermiculations on the head and operculum. A key feature is the ocellus (black spot with a golden halo) at the base of the caudal fin.

Posição da boca

terminal

Características distintivas

Prominent ocellus (eye-spot) on the caudal fin base, Three distinct vertical bars or blotches on the flanks (though some species may have more or less defined patterns), Large mouth with numerous small, conical teeth, Often a nuchal hump (forehead bump) in mature males, particularly during spawning, Robust, elongated body typical of a predatory fish

Nadadeira dorsal

Long, continuous dorsal fin, typically with a spiny anterior portion and a soft-rayed posterior portion. The spiny rays are strong and sharp.

Nadadeira caudal

Large, rounded to slightly emarginate caudal fin, providing powerful propulsion.

Dicas de identificação

1. 1

   Caudal Ocellus

   All Cichla species possess a distinct black spot (ocellus) with a light halo at the base of the caudal fin. This is a primary distinguishing feature from other large cichlids.

2. 2

   Body Pattern

   Observe the number and configuration of vertical bars or blotches on the flanks. For example, C. temensis often displays three prominent bars, while C. ocellaris may have more irregular blotches. Some species, like C. monoculus, have a single large lateral blotch.

3. 3

   Nuchal Hump

   Mature males, especially during breeding season, develop a pronounced fatty hump on their forehead. This feature is less developed or absent in females and juveniles.

4. 4

   Coloration

   Note the overall body color and any iridescent markings. These can vary significantly between species and even within populations of the same species depending on habitat and mood.

5. 5

   Fin Morphology

   Examine the shape and size of the fins, particularly the caudal fin, which can be rounded or slightly emarginate depending on the species.
