...Sara L. Jensen; Magnus L. Aaskov; Hans Malte; Mark Bayley ABSTRACT Air-breathing fish risk losing aerially sourced O 2 to hypoxic water during branchial passage. Two adaptations thought to mitigate this loss are reduced gill size and increased blood O 2 affinity. Both are affected by temperature...

.... Here, we examined the structure and function of Hbs in an amphibious, facultative air-breathing fish, the blue-spotted mudskipper ( Boleophthalmus pectinirostris ). We also characterized the genomic organization of the globin gene clusters of the species and we integrated phylogenetic and comparative...

... is predicted to result in relatively lower Hb–O 2 affinity in air-breathing animals. Consistent with this hypothesis, the air-breathing fishes Protopterus annectens, Polypterus senegalus and Clarias lazera all reduce Hb–O 2 affinity during the ontogenetic shift from breathing in water to breathing in air...

Abe; Tobias Wang SUMMARY Synbranchus marmoratus is a facultative air-breathing fish, which uses its buccal cavity as well as its gills for air-breathing. S. marmoratus shows a very pronounced tachycardia when it surfaces...

... used the gills as gas-exchange surfaces since no rich vascularization occurred in the mouth linings. As is known for other air-breathing fishes, f AB increased with decreasing water P O 2. Both buccal gas volume ( V B ) and inspired volume ( V I ) were significantly correlated with body mass ( M b...
