The biodiversity of marine life is limited given the islands' isolation, making identifying the impacts of invasion difficult. While much of the marine life is unknown there has been an invasive species identified in the waters around the islands. This species includes the South American silver porgy ("Diplodus argenteus argenteus") which is thought to have sought refuge in the area due to the wreck of an oil platform off the coast of Tristan in 2006. The silver porgy is omnivorous but is not linked to the consumption of the valued lobster populations that the islanders fish. The silver porgy is however suspected to be consuming components of the islands’ fragile kelp forest. The giant kelp forests of "Macrocystis pyrifera" were extremely limited in biodiversity and has a simple, short-chain food web. While this species is considered non-native and invasive, removal efforts are currently not prioritized. Continued monitoring is suggested and expedition research for all invasive marine species are ongoing..
