'Ota 'ika

Ota ika is a Oceanian dish consisting of raw fish marinated in citrus juice and coconut milk. The Tongan, Tahitian, and Samoan variants are essentially identical in that the raw fish is briefly marinated in lemon or lime juice until the surface of the flesh becomes opaque. The fish is then mixed with coconut milk and diced vegetables (most commonly cucumber, tomato, onion, green onion, and spicy peppers). This is the national dish of Tonga.

The word "ota" means "raw" within the Polynesian language group, although the more common term for the dish in French Polynesia is its French equivalent, "poisson cru" (literally, "raw fish"). Any type of seafood can be used to make "ota," the word "ika" means fish ("i'a" in Samoan language), but the dish is often prepared with mussels ("ota pipi/maso"), prawns ("ota ulavai"), crab ("ota pa'a/paka"), lobster ("ota ula"), octopus/squid ("ota fe'e/feke"), sea urchin ("ota vana/tuitui"), and eel ("ota pusi").

Similar dishes
A very similar dish are the kinilaw and ata-ata of the Philippines, and its descendant dish, the kelaguen of the Marianas Islands. The poke and lomi salmon of Hawaii are also similar. It is also similar to the Latin American ceviche, though the latter is relatively recent and may be a derivative dish, as citruses are not native to the Americas.
