Casuai

Casuai is a small, uninhabited island located in the Pacific Ocean, part of the Tuamotu Archipelago in French Polynesia. Situated within the Lagons de Tahiti National Park, it lies approximately 30 kilometers northwest of the island of Tahiti. The island is characterized by its low-lying coral atoll, with a narrow land area surrounded by a lagoon and the open ocean.

Casuai is primarily of scientific interest due to its ecological significance. The island serves as a nesting site for various seabirds, including the red-footed booby (*Sula sula*) and the brown noddy (*Anous stolidus*). Its lagoon is home to diverse marine life, including coral reefs, fish, and other marine organisms, contributing to the overall biodiversity of the region.

Geographically, Casuai is composed of a central sand islet surrounded by a shallow lagoon. The island lacks freshwater sources, making it unsuitable for permanent human habitation. Its isolation and natural state have preserved its pristine environment, attracting researchers and conservationists.

Due to its remote location and lack of infrastructure, Casuai is not accessible to the general public. Access is restricted to authorized personnel, such as scientists and park rangers, who conduct studies and monitoring to protect the island’s fragile ecosystem. The French Polynesian government, along with conservation organizations, plays a role in managing and preserving the island’s natural heritage.

Casuai’s name likely originates from the Polynesian language, though its exact etymology is not widely documented. The island remains a vital part of the broader Tuamotu Archipelago, contributing to the region’s ecological and cultural significance.
