Gill slits are individual openings to gills, i.e., multiple gill arches, which lack a
single outer cover. Such gills are characteristic of cartilaginous fish such as
Shark gills. Sharks have 5-7 pairs of gill slits located on the sides of their heads.
They breathe through these gill slits.
Sharks use their gills to absorb oxygen from the water. Most sharks have five gill
slits on each side of their body, behind the mouth and above the pectoral fins.
