Because they use jet propulsion from their nostrils.
I think that dolphins are probably faster than blue whales because dolphins are smaller than whales. Blue whales are MASSIVE and HUGE and they take a really slow time to get from one place to another. Dolphins are much smaller than blue whales, therefore, they're probably faster.
to catch prey
There are some species of sharks that can swim faster than dolphins (some sharks eat dolphins) but there are on the other fin, species of shark that dolphins are faster than. Mako sharks for instance, do swim at bursts of speed of 50 miles per hour making makos the fastest animals in the ocean. On average speed wise, between dolphins and sharks 50/50. Hope this answers the question.
No scientific research actually shows that dolphins are faster then sharks for one reason. They can swim about 24 miles an hour next to a boat for ten to thirty minutes which a shark could only swim for a short amount of time to catch it's food. It's like a speed boost. So dolphins are faster then sharks!
Orcas are faster than dolphins in the water.
faster
Sharks can swim faster than several ocean animals, including smaller fish like sardines and mackerel, which they often prey upon. Additionally, many species of squid and some smaller cephalopods are generally slower than sharks. While larger marine animals like dolphins and some species of tuna can reach high speeds, many sharks, such as the great white or shortfin mako, can outpace these creatures in short bursts.
Yes. I don't know of a human that can swim faster than a boat. You should know this.
yes
yes faster than you
yes they can.
you can swim faster under water because the water pulls you forward more than the air does
