Amphibious fishes: evolution and phenotypic plasticity.
Amphibious fishes spend part of their life in terrestrial habitats. The ability to tolerate life on land has evolved independently many times, with more than 200 extant species of amphibious fishes spanning 17 orders now reported. Many adaptations for life out of water have been described in the literature, and adaptive phenotypic plasticity may play an equally important role in promoting favou...
متن کاملRespiration of the amphibious fishes Periophthalmus cantonensis and Boleophthalmus chinensis in water and on land.
1. The routine oxygen consumption by Periophthalmus cantonensis and Boleophthalmus chinensis in water increased geometrically, whereas that in air increased logarithmically with temperature. At temperatures of more than 20 degrees C the oxygen uptake of both species was greater in water than in air. 2. When the fishes were able freely to select either an aquatic or terrestrial habitat, the tota...
متن کاملMudskipper genomes provide insights into the terrestrial adaptation of amphibious fishes
Mudskippers are amphibious fishes that have developed morphological and physiological adaptations to match their unique lifestyles. Here we perform whole-genome sequencing of four representative mudskippers to elucidate the molecular mechanisms underlying these adaptations. We discover an expansion of innate immune system genes in the mudskippers that may provide defence against terrestrial pat...
متن کاملAspects of the physiology of terrestrial life in amphibious fishes. III. The Chinese mudskipper Periophthalmus cantonensis.
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 ...
متن کاملAmphibious Modular Robotic Astrobiology
This paper presents the design of a robot that can traverse land, water, as well as quicksand-like mud. The robot is low cost and modular allowing the replacement of a variety of arms suitable for many of the tasks associated with astrobiological exploration. An astrobiologist on a field study will spend most of the time walking around and exploring the site looking for areas of interest which ...
