Branchial arches or gill arches are a series of paired bony / cartilaginous "loops" behind the throat (pharyngeal cavity) of fish, which support the fish gills. As chordates, all vertebrate embryos develop pharyngeal arches, though the eventual fate of these arches varies between taxa.

Fish gills are organs that allow fish to breathe underwater. Most fish exchange gases like oxygen and carbon dioxide using gills on both sides of the pharynx (throat). Gills possess tissues resembling short threads, referred to as gill filaments or lamellae.

2023年1月2日 · The gills of a fish are the organs that allow fish to breathe in water. A typical fish gill is made up of 3 parts. These three basic components are, Gill Arch; Gill Filament; Gill Lamellae; 1. Gill Arches (Branchial Arch) These are bony or cartilaginous structures that support the gill filaments. The gill arch basically support the gill ...

2025年2月7日 · The gill system consists of mainly four pairs of gill arches in most teleost fishes, such as sea bass, sea bream, grouper, and red porgy, etc., while it consists of three pairs of gill arches in pufferfish and striped-red mullet fish.

2025年2月7日 · The gill system consists of mainly four pairs of gill arches in most teleost fishes, such as sea bass, sea bream, grouper, and red porgy, etc., while it consists of three pairs of gill...

2025年2月7日 · This systematic review highlights the similarities and variations in gill morphology, histology, and anatomical structure between differing fish species. The gill system consists of mainly four pairs of gill arches in most teleost fishes, such as sea bass, sea bream, grouper, and red porgy, etc., wh …

2023年4月1日 · Fish gills not only play a role in respiratory metabolism, toxin degradation, and excretion but also are the main habitat and multiplication space for many species of fish bacteria. Carp and zebrafish have special ammonia oxidizing bacteria and denitrifying bacteria in their gills which play a role in nitrogen circulation.

All modern fishes have four respiratory gill arches and a 5th non-respiratory arch on each side of the buccal cavity. Each respiratory arch is composed of a cartilaginous supporting structure which bears gill rakers in the front and respiratory tissue in the rear.

Advanced types of gill-arch dentition were found to characterize most of the major groups of fishes. These types, combined with characters of the gill-arch endoskeleton and related muscles, provided a basis for discussion of the phyletic interrelationships of all major fish groups represented in the Recent fauna.

2023年1月1日 · The gill arches are well developed and support filaments of average length. The operculum covers over the whole of the gill system and communicates with the exterior via a more or less continuous slit. The lamellae are average in size, and their frequency on each side of a filament is usually about 18 to 25 per millimeter.
