Species
Four species are presently recognized by FishBase in this genus:
- Heros efasciatus Heckel, 1840
- Heros notatus (Jardine in Schomburgk, 1843)
- Heros severus Heckel, 1840 – also known as severum or banded cichlid
- Heros spurius Heckel, 1840
Some authorities recognize a fifth species, H. appendiculatus Castelnau, 1855, but it is treated as a synonym of H. efasciatus by FishBase. Fish belonging to the genus Heros are distinguishable by their bulbous "Dell 'Abate" lips and sedentary demeanor, especially after eating.

Famous quotes containing the word species:
“Nature seemed to have adorned herself for our departure with a profusion of fringes and curls, mingled with the bright tints of flowers, reflected in the water. But we missed the white water-lily, which is the queen of river flowers, its reign being over for this season.... Many of this species inhabit our Concord water.”
—Henry David Thoreau (1817–1862)
“Any reading not of a vicious species must be a good substitute for the amusements too apt to fill up the leisure of the labouring classes.”
—James Madison (1751–1836)
“The principle of avoiding the unnecessary expenditure of energy has enabled the species to survive in a world full of stimuli; but it prevents the survival of the aristocracy.”
—Rebecca West (1892–1983)
