The world’s rarest whale, the elusive spade-toothed whale, may have washed up on a beach in New Zealand, sparking excitement among marine scientists.
This event could provide unprecedented insights into a species that has never been seen alive and remains largely mysterious.
Unveiling a Marine Mystery
A 16.5-foot male whale washed ashore near the mouth of the Taieri River in Otago, on New Zealand’s South Island. Local officials quickly transported the whale to cold storage, preserving it for further study.
The Department of Conservation (DOC) announced the discovery, identifying the creature based on its distinctive coloring, beak, and teeth. DNA testing, which could take several weeks, is underway to confirm its identity as a spade-toothed whale, Forbes reports.
According to Gabe Davies, DOC’s coastal Otago operations manager, “From a scientific and conservation point of view, this is huge.”
A Species Shrouded in Mystery
The spade-toothed whale, scientifically named Mesoplodon traversii, is one of the least known large mammalian species. First identified in 1874 from a lower jaw and two teeth collected on Pitt Island, the species has remained an enigma, NBC News reports.
Only six specimens have ever been documented, and none have been seen alive. This lack of live sightings has made it nearly impossible for scientists to study their behavior, diet, or habitat.
In 2010, two more spade-toothed whales were found dead on a New Zealand beach. Initially misidentified as Gray’s beaked whales, DNA testing later revealed their true identity. These specimens were buried before they could be dissected, preventing any detailed study, reports the New York Times.
The recent discovery in Otago offers a unique opportunity for scientists to finally dissect a specimen and gather crucial information about the species.
Scientific Significance
“This is going to lead to some amazing science and world-first information,” Hannah Hendriks, marine technical adviser for New Zealand’s Department of Conservation, told the BBC.
The carcass, preserved in cold storage, will allow researchers to dissect it and potentially map its relationship to other specimens, learn about its diet, and perhaps discover clues about its habitat.
New Zealand is a hot spot for whale strandings, with over 5,000 recorded since 1840, NBC News reports. The country’s shores have seen various marine mammals wash up, but the discovery of a spade-toothed whale is particularly significant due to its rarity.
Scientists hope to collaborate with local Māori iwi (tribes) to plan the examination of the whale, respecting the cultural significance of whales as a taonga, or sacred treasure.

Potential Discoveries
If the whale is confirmed as a spade-toothed whale, it could provide insights into its biology, diet, and habitat. Scientists are eager to study its stomach contents to learn about its diet and to examine its organs to understand how it lives and survives in the deep ocean.
“Everything we look at will be new to science,” said Anton van Helden, an adviser on marine species for New Zealand’s Department of Conservation, told the New York Times. Van Helden, who has studied spade-toothed whales for 35 years, is confident about the identification based on the whale’s distinctive features.

Collaboration and Conservation
Collaboration with local Māori iwi is crucial in the study and conservation of this whale. The Māori consider whales as sacred, and their participation ensures that the cultural significance is respected while scientific research is conducted, Forbes reports. The DOC stated that the discussions with the Māori community could take time due to the whale’s rarity and importance.
The potential dissection and study of this whale could lead to groundbreaking discoveries. The contents of its stomach could provide clues about its diet, and genetic analysis could reveal its relationship to other whale species, the BBC reports.
This could be a significant step forward in understanding the spade-toothed whale, one of the ocean’s most mysterious creatures.
As researchers prepare to study the whale, they hope to uncover new information about its biology, behavior, and habitat. This rare find underscores the importance of conservation and the need to protect our oceans’ most elusive inhabitants.
