New distribution records of the coconut crab (Birgus latro) in eastern Polynesia on Oeno Atoll, Henderson Island, and Ducie Atoll, Pitcairn Islands

Researchers have extended the known eastern range of coconut crabs (Birgus latro) by over 600 kilometers, documenting their presence on Oeno Atoll, Henderson Island, and Ducie Atoll in the Pitcairn Islands. This discovery challenges previous assumptions about the species' distribution limits in the Indo-Pacific region. While populations remain sparse, suitable habitat and prey suggest larger numbers may exist, particularly on Henderson Island. The study relied on narratives and occurrence records to identify these new distribution points. Edge-of-range populations are often vulnerable, but the remoteness of the Pitcairn Islands may provide protection from threats affecting other regions.
