Which type of fish is characterized by its consumption of plant material?

Herbivorous fish are characterized by their consumption of plant material, making them distinct in their dietary preferences. These fish possess specialized anatomical adaptations such as flat teeth or grinding plates, enabling them to effectively break down and digest a variety of aquatic plants and algae. Their diet primarily consists of vegetation, which plays a significant role in the aquatic ecosystem by helping to control algae growth and providing an essential food source for various marine organisms.

In contrast, carnivorous fish primarily consume other fish or animal matter, while omnivorous fish have a mixed diet that includes both plants and animals. Predatory fish are specifically understood to hunt and capture live prey rather than grazing on vegetation. Thus, the focus on exclusively consuming plant material accurately defines herbivorous fish and highlights their essential role in aquatic environments.
