Let’s join with CBES to learn the basic difference between Dolphins and Whales
- While dolphins tend to have well-defined dorsal fins, whales comparatively have tiny or even no dorsal fin (such as the Beluga Whale).
Whales have evolved over time to have fused neck vertebrae – an adaptation that helps them to support the weight of their heads, while some dolphins have flexible necks.
- Whales typically being much larger than their counterparts. This is especially true for the baleen whales which are some of the largest animals on the planet, like Blue and Fin Whales, and the larger toothed whales such as the Sperm Whale.
- Dolphins rely heavily on the use of echolocation for hunting and navigation. Dolphins will prey on fish and squid that they can grasp with their teeth, while baleen whales prey upon tiny crustaceans like krill and copepods.
- Baleen whales have two blowholes, while the toothed whales, and subsequently dolphins and porpoises only have one.
- Dolphins are leaner with torpedo-shaped bodies and elongated beaks.
- Dolphins (and toothed whales) have some of the largest brains relative to the body size of any animal and are highly intelligent. In fact, Killer Whales have the second-largest brain of any animal, only behind the Sperm Whale.
- Dolphins are highly social animals that live in large groups or pods of related animals, where they help each other hunt, play, and rear offspring. Meanwhile, the large whales tend to be more solitary, aggregating in shared feeding grounds or for breeding.
