Contents of repetitive elements in fish genomes. Several repetitive elements (REs), such as transposable elements (TEs), long and short interspersed nuclear elements (LINEs and SINEs, respectively) and long terminal repeats (LTRs) are shown both as total percentage in genome (A) or percentage relative to repetitive elements content (B). A taxonomy tree for the species analyzed is shown below. Species: Anabantiformes (Anates: Anabas testudineus, Betspl: Betta splendens, Masarm: Mastacembelus armatus), Carangiformes (Echneu: Echeneis naucrates, Serdum: Seriola dumerili, Serlal: Seriola lalandi dorsalis), Cichliformes (Astcal: Astatotilapia calliptera, Orenil: Oreochromis niloticus, Punnye: Pundamilia nyererei), Cypriniformes (Cypcar: Cyprinus carpio, Danrer: Danio rerio, Sinrhi: Sinocyclocheilus rhinocerous), Cyprinodontiformes (Funhet: Fundulus heteroclitus, Krymar: Kryptolebias marmoratus, Poefor: Poecilia formosa), Perciformes (Cyclum: Cyclopterus lumpus, Gasacu: Gasterosteus aculeatus, Sanluc: Sander lucioperca), Pleuronectiformes (Cynsem: Cynoglossus semilaevis, Parorb: Paralichthys orbignyanus, Scomax: Scophthalmus maximus), Salmoniformes (Huchuc: Hucho hucho, Onctsh: Oncorhynchus tshawytscha, Saltru: Salmo trutta), Labriformes (Labber: Labrus bergylta) and Tetraodontiformes (Takrub: Takifugu rubripes, Tetnig: Tetraodon nigroviridis)
