The first paper of this series (Gordon et al. 1969) defined our usage of the phrase 'amphibious fishes', surveyed the literature on the physiology of terrestrial adaptations in those amphibious fishes lacking speciali2ed accessory respiratory organs, and presented data on aspects of related adaptations in the amphibious mudskipper fish, Periophthalmus sobrinus. The point was made in that paper ...

Respiration and ion regulation are the two principal functions of teleostean gills. Mainly found in the gill filaments of fish, mitochondria-rich cells (MRCs) proliferate to increase the ionoregulatory capacity of the gill in response to osmotic challenges. Gill lamellae consist mostly of pavement cells, which are the major site of gas exchange. Although lamellar MRCs have been reported in some...

Quaternary climatic cycles have influenced marine organisms' spatial distribution and population dynamics. This study aimed to elucidate the evolutionary influences of contemporary and glacial physical barriers on the population structure, demography and colonization history of the mudskipper (Periophthalmus modestus) based on a mitochondrial gene segment (ND5) from 131 individual fish sampled ...
