Mudskippers are found in mangrove swamps in Africa and the Indo-Pacific; they frequently come onto land, and can survive in air for up to 3-1/2 days. [5] Mudskippers breathe through their skin and through the lining of the mouth (the mucosa) and throat (the pharynx). This requires the mudskipper to be wet, limiting them to humid habitats.
Aquatic animals generally conduct gas exchange in water by extracting dissolved oxygen via specialised respiratory organs called gills, through the skin or across enteral mucosae, although some are evolved from terrestrial ancestors that re-adapted to aquatic environments (e.g. marine reptiles and marine mammals), in which case they actually ...
Others may breathe atmospheric air while remaining submerged, via breathing tubes or trapped air bubbles, though some aquatic insects may remain submerged indefinitely and respire using a plastron. A number of insects have an aquatic juvenile phase and an adult phase on land. In these case adaptions for life in water are lost at the final ecdysis
The four-eyed creatures found in Antarctica have “powerful” and “large” front arms with claws, researchers said. ‘Large’ sea creature breathes with its legs, sucks prey with ‘straw ...
Sea turtles are air-breathing reptiles that have lungs, so they regularly surface to breathe. Sea turtles spend a majority of their time underwater, so they must be able to hold their breath for long periods. [57] Dive duration largely depends on activity.
These ancient lobe-finned fish had evolved multi-jointed leg-like fins with digits that enabled them to crawl along the sea bottom. Some fish had developed primitive lungs that help them breathe air when the stagnant pools of the Devonian swamps were low in oxygen.
All sea snakes have paddle-like tails and many have laterally compressed bodies that give them an eel-like appearance. Unlike fish, they do not have gills and must surface regularly to breathe. Along with Cetaceans, they are among the most completely aquatic of all extant air-breathing vertebrates. [5]
The fact that the osteology of the plesiosaur's neck makes it absolutely safe to say that the plesiosaur could not lift its head like a swan out of water as the Loch Ness monster does, the assumption that air-breathing animals would be easy to see whenever they appear at the surface to breathe, [144] the fact that the loch is too small and ...
