Published: November 23, 2021 Show If there were Sea Animal Olympics there would be several species that would swim in the final heat. Whales are some of the largest sea animals but are they also the fastest? More importantly, just how fast do whales swim? They
wouldn’t get a Gold, Silver or Bronze but they might place in the top 10. Whales, dolphins and porpoises (all part of the whale group Cetacean) have streamlined bodies, are mostly hairless and have strong tail fins. Some are the shape of a torpedo! The whale group is divided into two subgroups,
baleen whales (the larger whales like blue whale, fin whale and gray
whale) and toothed whales (smaller whales like dolphins, porpoise and belugas). Let’s take a look at some of the fastest whales and see how they compare to some of the other fastest swimmers. slowmotiongli/Shutterstock.com Whales can reach speeds of a little more than 20 miles per hour over sustained periods. However, in extremely short bursts some species can travel more than 30 miles per hour!
One reason dolphins and smaller Cetaceans can’t swim faster? Scientists have studied their speeds and found that a scientific phenomenon – known as cavitation – makes it extremely painful for dolphins to travel at more than 34 miles per hour. This puts a natural “upper bounds” for the speeds of dolphins and other whale species for all but short bursts. To discover more about whale speeds, we’ll break them down into toothed whales (which are generally smaller), and baleen whales. What are the fastest toothed whales?Circumnavigation/Shutterstock.com If you had to choose 3 whales to swim in the 800m freestyle you might want to go with these toothed whales. Similar to human swimmers, these whales have to breathe air so they come up for air 2-3 times a minute while fast swimming. They can hold their breath longer for deep dives but for distance swimming at fast speeds they need the additional oxygen for the cardio. Three of the fastest toothed whales are:
What are the fastest baleen whales?In the baleen whale division you would have a hard time choosing just one species, but these three would be some of the fastest. They are generally a bit slower than toothed whales, but with their massive size it is quite a sight to see a 80ft whale going 25 mph pass your boat!
What are the fastest sea animals?Al McGlashan/Shutterstock.com Now that we’ve looked at how fast whales can swim, let’s take a broader view of the oceans! If whales had to compete in an open category with other sea animals they would not have a chance of keeping up. Take a look at some of the fastest sea animals:
About the Author I'm a Wildlife Conservation Author and Journalist, raising awareness about conservation by teaching others about the amazing animals we share the planet with. I graduated from the University of Minnesota-Morris with a degree in Elementary Education and I am a former teacher. When I am not writing I love going to my kids' soccer games, watching movies, taking on DIY projects and running with our giant Labradoodle "Tango". What is a blue whale's top speed?Blue whales can reach speeds of 50 kilometres per hour (31 mph) over short bursts, usually when interacting with other whales, but 20 kilometres per hour (12 mph) is a more typical traveling speed. When feeding, they slow down to 5 kilometres per hour (3.1 mph). Blue whales are also the loudest animals on Earth!
What is the fastest whale on Earth?5. Fin whales are the fastest of all great whales capable of swimming up to 23 miles per hour (23 kmph).
Are blue whales faster than orcas?“Blue whales are fast, but orcas are faster,” he said. The event that Dr. Wellard and her team witnessed took place off the coast of Bremer Bay, a biologically-rich region where large numbers of orcas, blue whales and other cetaceans can be seen during certain times of the year.
Which is faster orca or dolphin?When not at risk or hunting, dolphins travel at a leisurely speed of 10 kilometers per hour (kmh), which they can easily maintain for long distances. Orcas are slightly slower, traveling at only 6 or 7 kmh.
