What is the Difference between Whales and Dolphins?

Dolphins and whales are two of the most incredible marine mammals. They are both Teil of the perform; however, the two types of aquatic mammals share similar characteristics with some notable differences in body shape and size, feeding behaviour, social behaviour, and other aspects.

For example, There are hundreds (if not thousands) of different types of cetaceans in existence today, but a few like the blue whale are the largest species of mammal alive today. The blue whale is the largest creature on Earth. 

On the other hand, dolphins are small, fast, and very agile. Dolphins are known as both highly intelligent and highly social. By contrast, the whale family has a much higher incidence of individual and small group behaviours.

Knowing the differences between dolphins and whales allows us to recognise the significant diversity of marine life and our responsibility to protect these incredible animals.

1. Size and Body Structure

We can see from the differences in physical size that there is a huge difference between whales and dolphins. The blue whale can be over 100 feet long.

Dolphins, however, are much smaller than whales, and they're also built for speed, meaning they can do acrobatic leaps much easier than whales can. 

In contrast, whales are larger and heavier-bodied than dolphins, which tend to have a more streamlined, torpedo-shaped body that allows them to swim faster.

2. Teeth and Feeding Habits

The majority of whales engage in feeding through their baleen plates, while only the sperm whale uses teeth to consume food.

 Although most dolphins feed exclusively on their conical-shaped teeth to catch fish or squid, there is a distinct difference in diet between these two categories of marine mammals, indicating some variation in feeding strategies and behaviours.

3. Social Behavior

Dolphins are social animals and live in pods, which are groups of dolphins that communicate with each other through body language; whistles and clicks; and sounds. 

Depending on which species they belong to, whales can either live alone or in groups. Generally speaking, whales have simpler forms of social structures than dolphins.

4. Breathing and Blowhole

Both whales and dolphins use blowholes to breathe because they are air breathing mammals that come to the surface to breathe when they need to. 

While most whales have two blowholes, dolphins only have one, which makes it easy to distinguish between the two.

5. Intelligence and Interaction with Humans

Dolphins are extremely intelligent creatures. They have the ability to solve problems, compete with and play against other dolphins. Dolphins are known to have good communication skills with humans as well as with other marine mammals. 

Though both whales are intelligent, whales tend to migrate more than dolphins do and tend to have fewer social relationships if at all.

Conclusion

As stated earlier, while both dolphins and whales occupy similar categories in the family of cetaceans, the two species are distinct from each other.

Understanding these distinctions will help us tobetter appreciate the numerous species of marine mammals and their ecosystems present in our oceans today.
