  ADW: Lepidosiren paradoxa: Information
Lepidosiren paradoxa is found in the neotropics of South America, including Argentina, Bolivia, Brazil, Columbia, French Guiana, Paraguay, Peru, and Venezuela (Planquette et al., 1996).
Lepidosiren paradoxa are primarily freshwater fish and are physiologically unable to cross large expanses of saltwater (Alves-Gomes et al., 2003).
Lepidosiren paradoxa has not been well studied in terms of life span, but the studies that have been conducted show that the average lifespan of this species is a little more that eight years, both in the wild and in captivity.

Lepidosiren paradoxa (pirambóia) is the single representative of Dipnoan (lungfish) in South America.
Lepidosiren paradoxa, known as "pirambóia", is the unique representative of South American Dipnoan group, with true lungs.
Based on the literature, the main genetic characteristics of Lepidosiren paradoxa can be summarized as follows: (i) low diploid chromosome number; (ii) absence of chromosomes in the acrocentric state; (iii) enormous size of individual chromosomes; and (iv) high contents DNA (Ohno and Atkin, 1966; Oliveira et al., 1988).

He named the creature Lepidosiren paradoxa: lepido for the scales on its back, siren for the amphibians, and paradoxa for his confusion.
Lungs were surely the most tetrapodlike trait of Lepidosiren, the organs that let them survive on land, as opposed to gills which let fish breathe water.
As more specimens of Lepidosiren were studied it became clear, for example, that despite Owen's claims they did have nostrils -- or at least nostril-like passageways -- that connected into their mouths.

The obligate airbreather Lepidosiren inhabits rivers and lakes both in tropical (Amazon) and subtropical (Pantanal) regions.
Burrowed individuals show a dramatic increase in the airbreathing frequency (sevenfold), while the heart rate remains — with the exception of during the first hours in the mud, when a bradycardia occurs — unaffected.
Lepidosiren does not show a similar change in the airbreathing rate when submitted to graded hypoxia.

The extant lungfishes (Dipnoi) represent a link in the vertebrate transition from water- to airbreathing, show physiological characters similar to those of the tetrapod ancestors (rhipidistians) and possess a true paired lung, which evolved from the air-bladder.
In the present study heart rate, airbreathing rate and gill ventilation rate of active, aquatic and of inactive, burrowed South American lungfish have been measured in situ on a diurnal basis.
Our results offer a quantification of the short term cardiovascular alterations, that were observed in Lepidosiren in its natural habitat during exposure to severe aquatic hypoxia and in response to the partial drying up of the habitat.

 The Evolution of Man — Volume 2 eBook
The paleozoic Dipneusts that are in the direct line of our ancestry, and form the connecting-bridge between the Ganoids and the Amphibia, differ in many respects from their living descendants, but agree with them in the above essential features.
This is confirmed by a number of interesting facts that have lately come to our knowledge in connection with the embryonic development of the Ceratodus and Lepidosiren; they give us important information as to the stem-history of the lower Vertebrates, and therefore of our early ancestors of the paleozoic age.
With the phylogenetic study of the four higher classes of Vertebrates, which must now engage our attention, we reach much firmer ground and more light in the construction of our genealogy than we have, perhaps, enjoyed up to the present.

After I had dragged myself up onto the couch, the fish proceeded to impart to me a fascinating tale he had heard as a young fish.
So, here now is the story I was told by a hookah smoking lepidosiren named Gilligan.
One day, this man was going about his favorite hobby: that being looking up dirty words in the dictionary, and was in the "P's" when a beserk phlebotomist suddenly leapt out of the dictionary and stabbed the poor gymnosophist to death with a plastic knife(it took the better part of two days).
