What do black Nerita eat?

Black Nerita, a type of marine snail, primarily feed on algae and biofilm found on rocks and other surfaces in their intertidal habitat. They use their radula, a tooth-like structure, to scrape off these food sources. In some cases, they may also consume detritus and organic matter that accumulates in their environment. Their diet contributes to maintaining the health of their ecosystem by controlling algae growth.
