He respiratory system of the various species occurs in different ways, including in the gills. next some gill breathing examples.
What is gill breathing?
It’s one of the types of breathing which is produced in the gills gutswhich are structures located externally or internally in the species.
These structures are capable of absorbing oxygen circulating in the watergoing through an oxygenation process until the aquatic animals expel it abroad in the form of carbon dioxide.
This process is similar to that carried out by other animal species such as those that breathe through the windpipe, fur (stomata) or the lungs.
Starting from the definition, we will take as references the animals that take this route through the examples of gill breathing.
Examples of Gill Breathing
1. Manta ray
This marine species has external gills covered with cartilage, which makes your breathing easier and easier to produce.
As for the location of the gills, they are found in the lower region of its body or the distal portion at the base of its fins.
Consequently, they feed and produce their respiration, in addition, they contribute to the harmonic balance in the ecosystem marine thanks to carbon dioxide.
2. Shark
Regardless of the species of shark, these aquatic animals breathe through their gillshaving a composition similar to that of the manta ray.
Regarding respiration, the cartilaginous tissue that covers the gills facilitates the passage of water and oxygen, promoting gas exchange.
In this way, they obtain oxygen, breaking down the essential chemical elements and transforming the carbon dioxide that will go outside.
3. Tadpoles
The amphibians like frogs or toads, they undergo various changes or metamorphoses until they become adults.
In their secondary or tadpole stage before entering the adult phase, amphibians adapt their feeding and breathing to aquatic conditions.
Not having well-developed lungs, they adopt temporary gills, which allow their respiratory development and their subsistence in the marine world.

4. Frog
In the same way that in its secondary stage, before entering adulthood, the frog adopts gill breathing as primary, prior to its final phase.
These species of amphibians have gills on both sides of their body, which disappear as their physical constitution matures.
Subsequently, when they become frogs, the breath they take is ultimately skin and lung.
5. Octopuses
The cephalopod mollusks are one of the examples of marine animals that breathe through gills.
In order for them to breathe through this structure, they need extra organs, such as three hearts, two of which participate in gas exchange.
Therefore, the oxygen that passes to the gills connects with the two hearts and they pump blood for the oxygenation of this element.
Subsequently, they carry the oxygenated blood towards the third cardiac chamber so that it is distributed in the other tissues of the cephalopod.
Finally, the remaining oxygen breaks down into carbon dioxide and is expelled outside in this form to be the culminating point of gas exchange.
6. Axolotl
Another amphibian is part of the list and the axolotl is a member of the endemic nature of Mexico.
This species of amphibian has 6 gills that are distributed at the base of the head and its posterior portion.
Thus, they take oxygen from the water and participate in gas exchange up to the peak of carbon dioxide.
7. Squid
The squid They are part of the groups of cephalopod molluscs that inhabit the extension of all continents.
These have two gills, which facilitate breathing in the depths of the sea.
For their part, the gills are located near two tentacles, the latter attached to their particular anatomy that allows obtaining food or marine prey.
In this way, squids are such complex animals that they make their breathing easy by the gifts of nature.
8. Crabs
Crabs lead a double life, some are more on land than in the water, but that does not mean that in aquatic weather they do not breathe through their gills.
It should be noted that the gills of the crabs are located under a wide structure, called the shell and close to the front legs.
Therefore, when submerged in the water, they take in the circulating oxygen and enter a diffusion phase, with the intervention of a membranous tissue.
Subsequently, it reaches the bloodstream and the rest is expelled through the gills of this crustacean.
As a curious fact, crabs dive to obtain some food, but especially to reproduce or court their future partner.
9. Fish
Marine life has a wide range of specimens, including fish, which can be small or large.
They have gills on both sides of the base of the head, which facilitates gas exchange and their existence in the sea.
Unlike piranhas, the vast majority of fish do not have an oxygen reserve and therefore die after spending a reasonable amount of time outdoors.
10. Piranha
Finally, we close with the list of examples of gill breathing in marine animals, with the fearsome piranha.
This toothed fish has a pair of gills, very similar to other fish species, which allow aquatic respiration without any inconvenience.
For their part, they favor gas exchange and, as a curious fact about piranhas, while they eat, they breathe at the same time through the gills that connect at the base of the skull.
Although, these species can survive in external conditions, but it is due to the reserve of oxygen that they obtain in the depths of the sea.
