Herbivorous turtles: Many turtle species, such as the green sea turtle and the Galapagos tortoise, are primarily herbivores, feeding on leaves, fruits, and other plant material.

Herbivorous fish: There are numerous herbivorous fish species, including surgeonfish, parrotfish, and tangs. These fish feed on algae and seaweed, playing a crucial role in maintaining healthy coral reef ecosystems.

Herbivorous marine mammals: While many marine mammals are carnivorous, some, like manatees and dugongs, are herbivores, feeding on seagrasses and other underwater plants.

Viviparous snakes: Not all snakes lay eggs; some, like boas, vipers, and sea snakes, are viviparous. This means they give birth to live young that have developed inside the mother's body.
