Usage Notes
This dataset is intended for researchers and analysts studying shark attack patterns, environmental influences on shark behavior, and risk factors associated with human-shark interactions. It provides comprehensive details necessary for performing statistical analyses and comparative studies between New Caledonia and Reunion Island.

Data Sources
The data has been compiled from various local and international databases, publications, and eyewitness accounts to ensure accuracy and completeness.

The nocturnal feeding behavior and zoogeographical habitat of cookiecutter sharks Isistius brasiliensis and Isistius plutodus (Isistius spp.) greatly reduces interaction of this species with live humans. Attacks on live humans are exceedingly rare with 7 cases reported worldwide, 6 of them in Hawaiʻi, and 5 of these occuring among channel swimmers. Published research suggests that periods of bright moonlight may increase Isistius spp. contact with live humans and does not otherwise identify significant trends or risk factors. Yet 5 of the 6 Isistius spp. bites on live humans in Hawaiʻian waters occurred with the moon set and after nautical twilight end and before nautical twilight start. From 1961–2023 in Hawaiʻi, 129 successful solo channel crosses and 5 Isistius spp. related injuries in the habitat of cookiecutter sharks were analyzed across two groups: one where both the moon and sun were set (dark group) and one where the moon and/or sun was in the sky (light group). There was a significant difference for swimmers bitten by Isistius spp. in the dark 4 (12%) versus light groups 1 (1%), p = 0.012, RR 12.6 (95% confidence interval: 1.5–108.9). Swim start time and year was also significant (Pearson correlation 0.566, p
