It has highly folded lamellae which increases the surface are crucial for gas exchange .

The gills also have a long series of gill slits opening to the exterior .

Gill Structure for General Fishes

The gill has filaments which provide large surface area of blood capillaries which are one cell thick for diffusion .

Gill rakers serve to protect the gill from large debris and to trap food, particularly plankton.

Adaptation of Gills to its Function

Present of gill filaments for transfer of ions and water as well as exchange oxygen , carbon (IV) oxide .

It has gill slits to prevent external mechanical damage .

Gill rakers serve to protect the gill from large debris and to trap food, particularly plankton.
