While you may not know all about whales by now, there is a big difference between sperm whales and blue whales. What characteristics do these two beautiful and awe-inspiring creatures share, which classify them as individuals? If you’ve always wanted to learn more about whales, you’ve come to the right place!
In this article, we’ll review the Sperm Whale and the Blue Whale, and how they compare and contrast with each other. We’ll address differences in their appearance and behavior, as well as their preferred habitat and lifespan. By doing so, you should have a solid overview of these two majestic creatures. Now let’s get to know the whales!
Comparing Sperm Whales and Blue Whales
|sperm whale||blue whale|

Key Differences Between Sperm Whale and Blue Whale
There are a number of key differences between sperm whales and blue whales. Blue whales are much larger in length and weight than sperm whales. Also, blue whales are blue while sperm whales are gray. Finally, sperm whales live slightly longer compared to common blue whales.
Let us now discuss all these differences in more detail.
Sperm Whale vs. Blue Whale: Size
There are some notable differences between the average size of a blue whale and that of a sperm whale. In length and weight, blue whales are superior to ordinary sperm whales. But how much? Now let’s take a closer look at the numbers.
Depending on sex and age, blue whales average between 80 and 100 feet in length, while sperm whales average only 50-60 feet. Furthermore, the average weight of a sperm whale is 35-45 tons, while blue whales often reach a weight of 100-160 tons. This is a very noticeable difference between the two creatures, and it also affects their overall appearance. Let’s talk more about this.
Sperm Whale vs Blue Whale: Appearance
You can tell some remarkable physical differences between sperm whales and blue whales just by looking at them. Not only are the two whales very different in size, but they are also different in color. For example, sperm whales have dark gray to light gray coverings, while blue whales have varying shades of blue. But that’s not the only physical difference between them. Now let’s talk a little more about this.
For example, the head of a sperm whale is more bulbous and larger compared to that of a blue whale. In addition, blue whales are much more slender and more slender than the large, shapely bodies of sperm whales. Blue whales also have large ridges on their throats and mouths, while gray whales do not have this feature. Finally, sperm whales have one asymmetric blowhole, while blue whales have two blowholes.
Sperm Whales vs. Blue Whales: Locations and Habitats
There are some differences in the location and habitat preferences of sperm whales and blue whales. While these two species of whales are found in all oceans around the world, they both have specific places they like to spend their time. For example, blue whales migrate on average once or twice a year, while some sperm whales do not migrate regularly.
Depending on the time of year and the sex of the whale, you can find blue whales in cold and temperate waters, while sperm whales are mainly found off the coast of Alaska, the Pacific Islands and New England. If you’re interested in whale watching, paying attention to the migratory habits of these two beautiful creatures will ensure your success!
Sperm Whales vs. Blue Whales: Diet
The diet of sperm whales has some notable differences from that of blue whales. The blue whale is a baleen whale type, which means it uses its baleen to feed, while the sperm whale has teeth. This means that sperm whales usually eat fish, squid, sharks and other creatures, while blue whales mainly eat krill and occasionally fish.
Sperm Whales vs. Blue Whales: Lifespan
A final potential difference between sperm whales and blue whales has to do with their longevity. In general, sperm whales live longer on average than blue whales. For example, the average lifespan of a blue whale is 30 to 45 years, while that of a sperm whale is 30 to 60 years. However, there are many factors that affect the lifespan of the average whale, so keep this in mind when doing your own research!
I am broadly interested in how human activities influence the ability of wildlife to persist in the modified environments that we create.
Specifically, my research investigates how the configuration and composition of landscapes influence the movement and population dynamics of forest birds. Both natural and human-derived fragmenting of habitat can influence where birds settle, how they access the resources they need to survive and reproduce, and these factors in turn affect population demographics. Most recently, I have been studying the ability of individuals to move through and utilize forested areas which have been modified through timber harvest as they seek out resources for the breeding and postfledging phases. As well I am working in collaboration with Parks Canada scientists to examine in the influence of high density moose populations on forest bird communities in Gros Morne National Park. Many of my projects are conducted in collaboration or consultation with representatives of industry and government agencies, seeking to improve the management and sustainability of natural resource extraction.
