Satanoperca jurupari, the demon eartheater, is a species of cichlid endemic to the Amazon basin in South America.
Like some other Geophagini cichlids, the common name 'eartheater' is attributed to their common feeding strategy of sifting through substrate (e.g., sand, small rock, silt) for food, where mouthfuls of substrate are taken up and sorted in the buccal cavity for food items.
While generally considered to be an invertivore, it has been documented as an omnivore in systems that have been disturbed by human activity.
[1] This species is of little importance to local commercial fisheries but has grown in popularity among the aquarium trade over the past several years.
Parents will typically spawn in selected substrate and, after 24 hours, incubate eggs in the buccal cavity where young will seek refuge during the larval stage.
