A Note on Evidence for Pelagic Warm-Water Dolphins Resembling Lagenorhynchus

This note reviews new and historical sightings of Lagenorhynchus-like dolphins in tropical and sub-tropical waters of the Indian and Pacific Oceans. Given the distributions of the three Southern Hemisphere species, it seem probable that these sightings refer to an unrecognised species in tropical and sub-tropical waters. It is recommended that observers on future surveys in these regions are especially vigilant for sightings of these dolphins.
