Gills or gill-like organs, located in different parts of the body, are found in various groups of aquatic animals, including mollusks, crustaceans, insects, fish, and amphibians. Semiterrestrial marine animals such as crabs and mudskippers have gill chambers in which they store water, enabling them to use the dissolved oxygen when they are on land.


gills, external respiratory organs of most aquatic animals. In fishes the gills are located in gill chambers at the rear of the mouth (pharynx). Water is taken in through the mouth, is forced through openings called gill slits, and then passes through the gill clefts, spaces between the ranks of delicate gills, bathing them continuously.


gills, no matter what animal, allow the organism to syphon off the oxygen in the water, and bring it into their bloodstream. Crayfish need them to breathe underwater, just like any fish.

If you think fish don't have lungs, you're mostly correct. The vast majority of fish use gills to breathe; however, the lungfish is the exception, using lungs to breathe air above the water's surface. Some species of lungfish rely only on their lungs for breathing while others also take oxygen from the water through their gills.


Types of gills. Branched appendages: it is the most common form and occurs in molluscs, larvae, salamander and toad larvae and in annelids. Fish gills: They are common in all fish, they are pharyngeal clefts that connect with the digestive system of the animal, the water that enters the mouth of the fish will come out through the gills once the breathing process is completed.


23) Some animals have no gills when young, but then develop gills that grow larger as the animal grows larger. What is the reason for this increase in gill size? A) The young of these animals are much more active than the adult, which leads to a higher BMR (basal metabolic rate) and, therefore, a higher need for oxygen.


Some gastropods with gills live on land, and others with a lung live in the water. As well as the purely terrestrial and the purely aquatic animals, there are many borderline species. There are no universally accepted criteria for deciding how to label these species, thus some assignments are disputed. Terrestrialization


While all fish have gills, one fish also has lungs. The lungfish can survive when its water habitat dries up from seasonal drought. What an aptly named fish. There’s also certain land crabs that have both lungs and gills, and can breathe both under the sea and on land. The lungfish is a unique animal which has gills and lungs. Image from here.
