Aquatic Wildlife Atlas: Global Species Records is a large-scale aquatic animal observation dataset designed for aquatic ecological research and biodiversity analysis. It aims to provide researchers, students, and data scientists with high-quality aquatic ecological data resources and is widely used in species classification, biodiversity analysis, ecological modeling, environmental research, and machine learning tasks. This dataset contains 200,000 aquatic animal observation records, covering more than 100 aquatic species and encompassing major aquatic ecosystems worldwide, including coral reefs, tropical rivers, the Arctic Ocean, and deep-sea areas up to 7,000 meters deep. Each record corresponds to an independent biological observation and includes complete Linnaean taxonomic information (kingdom to species), ecological characteristics, physical measurements, geographic coordinates, environmental readings, and observation metadata.
