A social relationship was observed between a narwhal and a group of beluga whales in the St. Lawrence River. The narwhal had been accepted into the group of beluga whales and continued to travel with them. [25] A relationship between canines and a silkie chicken, coyote and a pygmy owl have all been documented. [26]
Belugas can be found in the far north of the Atlantic and Pacific Oceans; the distribution of narwhals is restricted to the Arctic and Atlantic Oceans. Monodontids have a wide-ranging carnivorous diet, feeding on fish, molluscs, and small crustaceans. They have reduced teeth, with the beluga having numerous simple teeth, and the narwhal having ...

In particular, the characteristic narwhal 'horn' is anatomically a tooth; the unidentified specimen lacked a single narwhal tusk, but its teeth were spiraled, like the tusk of a narwhal. [ 5 ] [ 3 ] The specimen had 18 teeth, an intermediate number when compared to the beluga (40 teeth) and the narwhal (one tooth).
