Fishs gills are made up of a gill bar, gill filaments, gill rakers and gill lamellae. They are used to filter food particles and other debris out of the water as it flows over the gills. Why are there many filaments and lamellae in fish gills? Epub 2012 Aug 16. In terms of the other types of gills we covered, we learned that cartilaginous aquatic animals, like sharks, have gill slits, which open directly to the outside of the body, and that they operate through a process called ram ventilation, where the animal has to swim constantly in order to push water over the gills. Rakers filter out any debris, such as food particles, from entering the animal's body cavity.
