A rare spade-toothed whale, one of the world’s most elusive marine species, was found on a New Zealand beach in July, marking a significant milestone for marine researchers. The 5-meter-long male whale, known to inhabit the Southern Pacific Ocean’s deep trenches, represents only the seventh specimen ever documented. Discovered near Dunedin, the whale was transported to a research facility for an unprecedented dissection. The species, first identified through skeletal remains in 1872, has remained enigmatic due to its infrequent appearances and the lack of live observations. Experts explained that the dissection, conducted in collaboration with Māori cultural representatives, aims to uncover crucial details about the whale’s biology, behavior, and habitat.

The meticulous dissection process incorporates scientific precision and cultural sensitivity, reflecting the importance of the whale as a “taonga,” or treasure, in Māori tradition. Observers noted markings from cookiecutter sharks, although these were not linked to the cause of death. Researchers expressed hope that examining the whale’s anatomy, including its auditory and digestive systems, would yield valuable insights. The skeletal remains will be preserved for public display, with 3D technology employed to replicate the jawbone and teeth. DNA evidence has confirmed the distinctiveness of the spade-toothed whale from other beaked species. The study also aims to explore potential parasitic species unique to the whale and identify how these findings could inform broader ecological and biological knowledge. The integration of indigenous knowledge and scientific inquiry underscores the importance of interdisciplinary collaboration in understanding rare marine species.
