A recently discovered dead whale on a beach in New Zealand has been identified as a spade-toothed whale, a species so rare it has never been observed alive. Scientists determined the identity of the five-meter-long beaked creature based on its color patterns, skull shape, beak, and teeth. The remains are currently in cold storage awaiting DNA testing, which could take several weeks to confirm the final identification.
Significance of the Discovery
The discovery of the spade-toothed whale carcass is significant due to the rarity of the species. With no live sightings and very few specimens, little is known about these whales. Researchers hope this find will provide crucial new information about the species. Gabe Davies, an official from the Department of Conservation (DOC), highlighted the importance of this discovery, noting that only six samples have ever been documented worldwide.
Local Involvement and Historical Context
The whale was found on July 4 at the mouth of the Taiari River in Otago province, on New Zealand’s South Island. Local officials were immediately notified. The New Zealand Māori people, who regard whales as sacred, will participate in decisions regarding the whale’s fate.
The spade-toothed whale species was first described in 1874 after a lower jaw and two teeth were collected from New Zealand’s Chatham Islands. Additional skeletal remains found off islands in New Zealand and Chile further confirmed the existence of this species. More recently, stranded whales found off New Zealand’s North Island in 2010 and 2017 added to the small collection of known specimens.
Potential for Scientific Advancements
The DOC stated that, because the specimen had only recently died, it might become the first whale of the species to be dissected. This could provide unprecedented insights into the biology and ecology of the spade-toothed whale.
