Many vertebrates have evolved life histories that allow them to colonize unique ecological niches and survive where others cannot. A great example are lungfishes, sarcopterygian fish that hold a key phylogenetic position as the closest relative to all tetrapods [1–4]. Lungfishes include 3 genera, the Australian lungfish (Neoceratodus forsteri), South American lungfish (Lepidosiren paradoxa), and the genus, Protopterus sp. that includes the 4 African lungfish species (P. annectens, P. aethiopicus, P. dolloi, and P. amphibius).
