What is the shark's gill stilts function?
Shark gill slits serve the vital function of allowing water to flow over the gills, where gas exchange occurs. As sharks swim, water enters the mouth and exits through the gill slits, facilitating the absorption of oxygen and the expulsion of carbon dioxide. Unlike bony fish, which have a single gill cover, sharks have multiple gill slits that enhance their ability to breathe efficiently in various aquatic environments. This adaptation is crucial for their survival, enabling them to thrive in diverse marine habitats.
