Algae (singular alga) is an informal term for a large, diverse group of photosynthetic organisms that are not necessarily closely related, and is thus polyphyletic.
The Amazon basin is the part of South America drained by the Amazon River and its tributaries.
Camouflage is the use of any combination of materials, coloration, or illumination for concealment, either by making animals or objects hard to see (crypsis), or by disguising them as something else (mimesis).
Cichlids are fish from the family Cichlidae in the order Perciformes.
In biology, detritus is dead particulate organic material (as opposed to dissolved organic material).
An egg is the organic vessel containing the zygote in which an animal embryo develops until it can survive on its own; at which point the animal hatches.
In biological classification, family (familia, plural familiae) is one of the eight major taxonomic ranks; it is classified between order and genus.
Fresh water (or freshwater) is any naturally occurring water except seawater and brackish water.
A genus (genera) is a taxonomic rank used in the biological classification of living and fossil organisms, as well as viruses, in biology.
Greek (Modern Greek: ελληνικά, elliniká, "Greek", ελληνική γλώσσα, ellinikí glóssa, "Greek language") is an independent branch of the Indo-European family of languages, native to Greece and other parts of the Eastern Mediterranean and the Black Sea.
The Guiana Shield is one of the three cratons of the South American Plate.
Invertebrates are animals that neither possess nor develop a vertebral column (commonly known as a backbone or spine), derived from the notochord.
Jacques Pellegrin (12 June 1873, Paris – 12 August 1944) was a French zoologist.
Jean-Pierre Gosse is a biologist who discovered a type of angelfish called Pterophyllum leopoldi.
Johann Jakob Heckel (23 January 1790 – 1 March 1857) was an Austrian taxidermist, zoologist, and ichthyologist from Mannheim in the Electoral Palatinate.
Monogamy is a form of relationship in which an individual has only one partner during their lifetime — alternately, only one partner at any one time (serial monogamy) — as compared to non-monogamy (e.g., polygamy or polyamory).
In biology, a mutation is the permanent alteration of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA or other genetic elements.
The Orinoco Basin is the part of South America drained by the Orinoco river and its tributaries.
Perciformes, also called the Percomorpha or Acanthopteri, are the most numerous order of vertebrates, containing about 41% of all bony fish.
Marine angelfish are perciform fish of the family Pomacanthidae.
Predation is a biological interaction where a predator (a hunting animal) kills and eats its prey (the organism that is attacked).
Pterophyllum altum, also referred to as the altum angelfish, deep angelfish, or Orinoco angelfish, occurs strictly in the Orinoco River Basin and the Upper Rio Negro watershed in Southern Venezuela, Southeastern Colombia and extreme Northern Brazil.
Pterophyllum leopoldi, also referred to as the teardrop angelfish, Leopold's angelfish dwarf angelfish, or roman-nosed angelfish, is an angelfish species native to the Amazon River (between Manacapuru and Santarém), Essequibo River and Rupununi River.
Pterophyllum scalare, most commonly referred to as angelfish or freshwater angelfish, is the most common species of Pterophyllum kept in captivity.
A reef is a bar of rock, sand, coral or similar material, lying beneath the surface of water.
Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together.
In taxonomy, an undescribed taxon is a taxon (for example, a species) that has been discovered, but not yet formally described and named.
