This is a method of gill ventilation that is used by many species of fish. Here we will go into more detail on each structure that makes up different gills. Gills are tissues that are like short threads, protein structures called filaments. The gill filaments are served by a dense network of blood vessels that ensure efficient transport of gases. About 2530 days after spawning, gill filaments are apparent as an outgrowth from the caudal side of the gill arches. The gills also regulate levels of mineral ions and the pH of the blood, as well as being the primary site of nitrogenous waste excretion, in the form of ammonia. The gill arches offer support for the gills as well as the blood vessels. Arteries that enter the gills bring blood with low oxygen and a high concentration of wastes. This means that Gill filaments are the red, fleshy part of the gills; they take oxygen into the blood.
