Respiratory function in the South American lungfish, Lepidosiren paradoxa (Fitz).
Few animal species have aroused as much excitement upon their discovery as the South American lungfish. Its possession of distinct piscine as well as amphibian characters made the animal a link in the transition of vertebrate life from water breathing to air breathing. Its special attributes are clearly reflected in its name, Lepidosiren paradoxa. Physiological experimentation on respiratory fu...
متن کاملSpecialized metabolism and biochemical suppression during aestivation of the extant South American lungfish--Lepidosiren paradoxa.
Lepidosiren paradoxa (pirambóia) is the single representative of Dipnoan (lungfish) in South America. This species is considered a living fossil, in spite of some reports describing this fish as having a very specialized life style. It aestivates during the dry season, and has developed metabolic adaptations to cope with both flooding and drought. The literature describing its tissue ultra-stru...
متن کاملEimeria lepidosirenis n.sp. (Apicomplexa:Eimeriidae) of the South American lungfish Lepidosiren paradoxa (Osteichthyes:Dipnoi) from Amazonian Brazil.
The mature oocysts of Eimeria lepidosirenis n.sp. are described in faeces removed from the lower region of the intestine of a single specimen of the South American lungfish Lepidosiren paradoxa, from Belém, state of Pará, Amazonian Brazil. Oocysts with endogenous sporulation: spherical to slightly subspherical, 30.8 x 30.3 microm (28.1 x 25.9 -33.3 x 31.8), shape-index (ratio length/width) 1.0,...

متن کاملRespiration in the African lungfish Protopterus aethiopicus. I. Respiratory properties of blood and normal patterns of breathing and gas exchange.
Members of the three existing genera of lungfishes represent different stages in the transition from aquatic to aerial breathing. Neoceratodus, the Australian lungfish, is primarily aquatic and utilizes gill breathing, while its lung offers an accessory means for O2 absorption (Lenfant, Johansen & Grigg, 1966; Johansen, Lenfant & Grigg, 1967). Conversely, the South American lungfish, Lepidosire...
