Wildlife of Tristan da Cunha: Remote South Atlantic Sanctuary

The world's most isolated inhabited archipelago hosts unique fauna:

• Seabirds: Northern rockhopper penguin, Tristan albatross, Atlantic petrel, great shearwater—millions breed here.
• Land birds: Endemic Tristan thrush, Wilkins's bunting, Inaccessible Island rail (world's smallest flightless bird).
• Marine mammals: Subantarctic fur seal, southern elephant seal, occasional orca.
• Introduced: Feral cats (on main island), house mice (on Gough)—conservation targets.
• Reptiles/Invertebrates: Endemic skinks, flightless moths, beetles.

Gough & Inaccessible Islands are UNESCO World Heritage Sites; strict biosecurity protects endemics.
