In a remarkable development for marine biology, a spade-toothed whale, one of the world’s rarest cetaceans, has been spotted on a beach in New Zealand, offering scientists a rare opportunity to study this elusive species. The creature, measuring approximately five meters long, washed ashore on an Otago beach earlier this month, and its unique characteristics have led conservationists to believe it is indeed a spade-toothed whale, a type of beaked whale known for its mysterious nature.
The identification was made by New Zealand’s Department of Conservation (DOC), which reported on Monday that the whale’s distinct color patterns, skull shape, beak, and teeth were critical indicators. “We know very little, practically nothing, about these creatures,” stated Hannah Hendriks, a Marine Technical Advisor for DOC. “This is going to lead to some amazing science and world-first information.”
If confirmed as a spade-toothed whale, this specimen would be the first of its kind found in a state suitable for scientific dissection. This would allow researchers to examine its anatomy, determine its dietary habits, and potentially uncover clues regarding its elusive habitat in the vast southern Pacific Ocean. Currently, there is no comprehensive understanding of the spade-toothed whale’s behavior, diet, or preferred environment, making this sighting particularly significant.
Historically, only six spade-toothed whales have been identified, with previous specimens found on New Zealand’s North Island having been buried before DNA testing could verify their species. The beached whale has been promptly transported to cold storage to preserve its condition, and researchers are collaborating with local Maori iwi (tribes) to discuss examination plans. In Maori culture, whales are considered taonga—sacred treasures of significant cultural value.
In a notable recent event, Pacific Indigenous leaders signed a treaty recognizing whales as legal persons, although this declaration lacks formal recognition in the laws of the countries involved. This new finding may enhance the ongoing discussions about marine conservation and the rights of cetaceans within the context of Indigenous beliefs.
The exact habitat of spade-toothed whales remains a mystery. These deep-diving creatures are believed to surface rarely, making it nearly impossible to pinpoint their locations beyond the vast southern Pacific Ocean, which includes some of the world’s deepest ocean trenches. “It’s very hard to do research on marine mammals if you don’t see them at sea,” Hendriks explained. “It’s a bit of a needle in a haystack. You don’t know where to look.”

Confirmation of the whale’s identity will involve genetic testing, which could take several months. Kirsten Young, a senior lecturer at the University of Exeter who has studied spade-toothed whales, expressed optimism about this discovery. “It took many years and a mammoth amount of effort by researchers and local people to identify these incredibly cryptic mammals,” she noted. “The fresh discovery makes me wonder how many are out in the deep ocean and how they live.”
The history of spade-toothed whales dates back to the discovery of the first bones in 1872 on New Zealand’s Pitt Island, followed by additional finds in the 1950s and 1986. It wasn’t until DNA sequencing in 2002 that researchers confirmed these specimens belonged to the same species, distinguishing them from other beaked whales. However, questions remained about whether the species was extinct until two more spade-toothed whales washed ashore in 2010, initially misidentified as other types of beaked whales. Tissue samples later revealed their true identity.
New Zealand is known as a whale-stranding hotspot, with over 5,000 recorded incidents since 1840, according to the Department of Conservation. Each stranding presents both a challenge and an opportunity for research, especially when rare species like the spade-toothed whale are involved. As scientists prepare to study this newly discovered specimen, the hope is that it will yield invaluable insights into a species shrouded in mystery and enhance our understanding of marine biodiversity.
