An individual Antarctic blue whale is re-sighted at South Georgia

Assembled from 41 blocks · 1 evidence · 45 related

1. Story
2. An Antarctic blue whale photographed in 2019 and nicknamed Magrathea is re-sighted during a 2026 survey conducted from a passenger vessel, matched through a shared photo-identification platform with contributions from non-specialist observers. A single re-sighting carries disproportionate weight for a subspecies whose entire abundance estimate rests on a catalogue of a few hundred individuals - which is also a statement about how thin the data still is.

40. Evidence
41. An Antarctic blue whale first photographed in 2019 and nicknamed Magrathea was re-sighted in 2026 during an ORCA survey conducted from a passenger vessel, matched through a shared photo-identification platform with contributions from non-specialist observers. V55 verification basis: this is an NGO field report retrieved in search summary, not a peer-reviewed record; it should be treated as a reported observation pending publication.
