Combtooth Hemot (Balaenami excelsus)
The combtooth hemot is a deeper dwelling species of Balaenami that, despite being an air breather, is rarely ever seen. Less than 80 specimens have been found since the discovery of the combtooth in 1892 and even with modern technology, there has been little success in finding them. Despite being a member of the largest genus of vertibrate animals alive, the combtooth, at least the specimens found, have only reached lengths of up to 7.3-8m (23-26ft). The longest specimen, nicknamed Ghost after her elusive nature, was also the oldest specimen. With the help of carbon dating, scientists were able to determine that Ghost was roughly 283 years give or take meaning she was likely born in 1734. Unfortunately in 2017, Ghost passed away from her old age. After appropriate study, her body was taxidermied and is now displayed at The Smithsonian Museum of Natural History. Ghost herself was a lighter grayish colour while many other combtooths have been seen as much darker, almost black, in colour. This suggests to scientists that perhaps the lighter colouring is an aspect of the combtooth's age, but it's difficult to tell with the small amount of information and data we have of these elusive creatures. The combtooth, in addition to its elusivity, is the most controversial in the scientific community. Many groups argue the combtooth should be classified as a separate genus from the genus Balaenami and instead in a new genus titled Prospodoidae due to its vastly different baleen dentition, which consists of tightly packed baleen that are so closely packed that they resemble the teeth of a comb, and its unusal lifestyle of solitude and deep diving. Others argue that the combtooth is merely an outlier of its genus with distincively different features from other species in the genus Balaenami due to different environmental and ecological pressures.
