The gills are the respiratory organ of the vast majority of aquatic animals and their function is to carry out the process of extracting the oxygen dissolved in the water.

Currently, two types of gills are known :

External: visible to the naked eye by the hollow walls exposed in the body.

Internal: they are gills that are partially closed and protected.

What are the animals that breathe through gills?

Among the various species of animals, we can mention three:

  1. Mollusks: they have their gills protected inside a cavity or open conduit, through which water circulates and extracts oxygen.
  2. Fish: most fish have gills, however, there are some aquatic animals that use lung respiration, such as whales, turtles, dolphins, among others.
  3. Vertebrates and insects: these types of animals in their initial stage breathe through gills, later, when they reach their adult stage, they change their type of respiration, adapting to the environment.
