Fishes have various modes of feeding. Fishes are herbivores, carnivores, parasites, filter feeders, and detritus feeders. One fish may even have several different modes of feeding, depending on the food available.

Fishes reproduce in a number of ways. Their eggs are fertilized either externally or internally, depending on the species. Some lay eggs. They are called oviparous. In ovoviviparous fishes, the eggs develop inside the female. The embryos are fed by an attached yolk sac. In viviparous fishes, the embryos get their food from the mother’s body, not from an egg.
