What other animals are similar to beluga whales?

* Narwhal: Narwhals are closely related to beluga whales and share many physical characteristics, including their large, bulbous heads and lack of a dorsal fin. However, narwhals are distinguished by their long, spiral tusks, which are actually elongated canine teeth.

* Killer whale: Killer whales (or orcas) are also related to beluga whales and share some of their physical characteristics, such as their large size and black-and-white coloration. However, killer whales are much larger than beluga whales and have a more powerful jaw and dentition.

* Pilot whale: Pilot whales are not as closely related to beluga whales as narwhals and killer whales, but they do share some similarities, such as their large size and social behavior. Pilot whales are found in deeper waters than beluga whales and are not as well-studied.

* Bottlenose dolphin: Bottlenose dolphins are not closely related to beluga whales, but they do share some similarities, such as their intelligence and social behavior. Bottlenose dolphins are found in warmer waters than beluga whales and are more commonly seen in coastal areas.
