A team of scientists, led by University of Auckland marine biologist Emma L. Carroll, originally set out to ensure that the long-thought \u201cdisjointed\u201d populations of the True\u2019s beaked whale<\/em> (Mesoplodon mirus<\/em>) truly were of the same taxonomic classification. They would soon figure out, however, that they have a new species of beaked whale on their hands.<\/p>\n\n\n\n

Almost a decade ago from the time of writing, a dead specimen of what appears to be just another True\u2019s beaked whale washed ashore off the coast of South Island, New Zealand. The beaked whale was named \u201cNihongore\u201d by the local Ng\u0101ti M\u0101haki tribe, who then sent off Nihongore\u2019s bones to the Te Papa Tongarewa Museum in Wellington.<\/p>\n\n\n\n

The taxonomic analysis of several beaked whale specimens revealed the potential range of the new Ramari\u2019s beaked whale, Mesoplodon eueu<\/em>. The yellow dots show beaked whale specimens obtained from the North Atlantic region, while black circles show specimens obtained from the Southern Hemisphere. Specimens from the North Atlantic include the lone specimen from New Zealand that\u2019s now determined to be of the new species. (Carroll et al, 2021) <\/figcaption><\/figure><\/div>\n\n\n\n

Now, some ten years later, taxonomic analysis of beaked whale specimens from museum and archival specimens revealed that a new species of beaked whale hid right under our noses this whole time: the newly-designated Ramari\u2019s beaked whale<\/em>, Mesoplodon eueu<\/em>. The new findings were published in the Proceedings of the Royal Society B: Biological Sciences<\/em>.<\/p>\n\n\n\n

\u201cInitially, we thought this was the first True\u2019s beaked whale found in [New Zealand], but that changed during our work with a global network of researchers,\u201d Carroll said in a statement. \u201cWe soon realized that the genetics and skull shape of True\u2019s beaked whales in the northern hemisphere were very different to True\u2019s beaked whales in the southern hemisphere. [\u2026] They have been separated for around half a million years, probably because they don\u2019t like the warm water near the equator. It\u2019s clear that they are different species.\u201d<\/p>\n\n\n\n

The new Ramari\u2019s beaked whale becomes the 24th known species in beaked whales, formally known with its systematic name Ziphiidae<\/em>. Beaked whales, also called ziphiids<\/em>, are considered some of the least-known groups of mammals on the planet, given their low abundance and very deep sea habitats. Despite these, Carroll and team consider these whales as among \u201cthe most visible inhabitants of the deep sea\u201d due to their size and distribution.<\/p>\n\n\n\n
