The ocean is inhabited by a diverse array of animals, including fish, marine mammals, invertebrates, crustaceans, and corals. Fish, such as tuna and clownfish, can be herbivores, carnivores, or omnivores, while marine mammals like dolphins and whales primarily feed on fish and squid. Invertebrates, including jellyfish and octopuses, vary in diet from predation to filter feeding. Crustaceans, such as crabs and shrimp, are mostly omnivorous, consuming algae and plankton. Corals and sea anemones capture small fish and plankton with their stinging tentacles. Together, these animals play vital roles in marine ecosystems, contributing to biodiversity and supporting human activities like fishing and tourism.
