Which fish and marine mammals are found in the Indian Ocean?

The Indian Ocean supports a diverse array of marine life, ranging from small reef-dwelling species to large marine mammals.

Fish

The ocean's tropical and subtropical waters host a variety of commercially and ecologically significant fish, including:
* Pelagic species: Various species of tuna, billfish, flying fish, mackerel, and sardines.21
* Coastal and reef species: Snappers, croakers, grunts, and numerous brightly colored reef fish.21
* Other species: Luminous anchovies, lantern fish, and various types of sharks.1

Marine Mammals

Several marine mammals inhabit the Indian Ocean, often utilizing its coastal regions for feeding and breeding:
* Dugongs: Also known as sea cows, these marine mammals inhabit warm coastal waters and feed on seagrasses.31
* Cetaceans: The ocean is home to various dolphins, including the bottlenose dolphin and the Irrawaddy dolphin, as well as both toothed and baleen whales.14
* Seals: These are also found in various parts of the ocean.1

It is essential to recognize that many of these species, particularly vulnerable animals like the dugong, face significant threats from habitat loss, pollution, and accidental entanglement in fishing nets, necessitating strong conservation efforts to protect these vital ecosystems.31
