Footage from the Rio Sucuri - a karst stream habitat in Mato Grosso do Sul, Brazil.

Footage shows the habitat of the clear water karst stream of the Rio Sucuri, in the Bodoquena highlands of Mato Grosso do Sul, Brazil. The first few km of the river are clear, having emerged from its source spring nearby and has not yet had time to become turbid from detritus and sediment. The clear waters permit plenty of sunlight penetration which in turn leads to dense aquatic vegetation. Plant species found here include: Acrosticum danaeifolium Bacopa australis Chara rusbyana Echinodorus cordifolius Echinodorus grandiflorus Echinodorus macrophyllus Gomphrena elegans Helanthium bolivianum (used to be known as Echinodorus bolivianus) Hydrocotyle verticillata (described in literature concerning this river as H. leucocephala but I’m sure that it’s H. verticillata) Ludwigia peruviana Myriophyllum aquaticum Nymphaea jamesoniana Nymphaea gardneriana Planch Potamogeton illinoensis Polygonum acuminatum Polygonum hydropiperoides Pontederia parviflora Fish species appearing in this video: Characidium laterale (Boulenger 1895) Characidium zebra Eigenmann 1909 Leporinus friderici (Bloch, 1794) Steindachnerina brevipinna (Eigenmann & Eigenmann, 1889) Prochilodus lineatus (Valenciennes, 1837) Bryconops melanurus (Bloch, 1794) Acestrorhynchus pantaneiro Menezes, 1992 Astyanax lacustris (Lütken, 1875) Hoplerythrinus unitaeniatus (Spix & Agassiz 1829) Hemigrammus tridens Eigenmann 1907 Hyphessobrycon eques (Steindachner, 1882) Jupiaba acanthogaster (Eigenmann, 1911) Moenkhausia bonita Benine, Castro & Sabino, 2004 Moenkhausia dichroura (Kner 1858) Moenkhausia forestii Benine, Mariguela & Oliveira, 2009 Moenkhausia oligolepis (Günther, 1864) Phenacogaster tegatus (Eigenmann, 1911) Brycon hilarii (Valenciennes, 1850) Salminus brasiliensis (Cuvier, 1816) Crenicichla lepidota Heckel, 1840
