Bikar (Bikaar) Atoll National Marine Sanctuary

Bikar Atoll is one of two remote, uninhabited northern atolls protected within the Republic of the Marshall Islands' first national marine sanctuary (announced 29 January 2025), which spans ~48,000 km2 (18,500 sq mi) and is fully protected from fishing. The atoll hosts grey/reef sharks, green sea turtle nesting colonies, giant clams, Napoleon (humphead) wrasse and bumphead parrotfish. All fishing — therefore spearfishing — is prohibited.
