Found predominantly in males, the tusk grows up to 10 feet (3 meters) long — and previous research has suggested it serves as a competitive display to secure mates. But now, with the help of ...
The narwhal was scientifically described by Carl Linnaeus in his 1758 publication Systema Naturae. [5] The word "narwhal" comes from the Old Norse nárhval, meaning 'corpse-whale', which possibly refers to the animal's grey, mottled skin and its habit of remaining motionless when at the water's surface, a behaviour known as "logging" that usually happens in the summer.
However, in narwhals the tusk is implanted in the left maxilla, whereas the tusk in Odobenocetops originates in the right premaxilla. The tusks in these two genera are therefore not homologous, and the occurrence of tusks in Odobenocetops is a convergence with narwhals. [4] In the holotype of Odobenocetops peruvianus both tusks are incomplete ...
An African elephant in Tanzania, with visible tusks. Tusks are elongated, continuously growing front teeth that protrude well beyond the mouth of certain mammal species. They are most commonly canine teeth, as with narwhals, chevrotains, musk deer, water deer, muntjac, pigs, peccaries, hippopotamuses and walruses, or, in the case of elephants, elongated incisors.
A former Royal Canadian Mounted policeman accused of smuggling $2 million worth of narwhal tusks into the United States is now in custody.
This tusk is from a small toothed Arctic whale called a narwhal. Only the male of the species develops this twisted growth, which originally forms from a tooth. For centuries such tusks, which could grow several metres in length, were claimed to be from the mythical creature the unicorn.
An obvious difference between African elephants and Asian elephants is their genera.These are two different species, with African elephants belonging to the genius Loxodonta and Asian elephants ...
This article is about the narwhal, or as it's sometimes known, the unicorn of the sea. With a tusk protruding out of its head, the narwhal is one of the strangest beasts I know of. Narwhals are notoriously hard to study in the wild, which could have implications for the protection and survival of the species. Special thanks to RoySmith and ...
