They include several big species whose common names contain "whale" rather than "dolphin", such as the Globicephalinae (round-headed whales, which include the false killer whale and pilot whale).
This allowed the team to measure the force exerted by a dolphin. Results showed the dolphin to exert approximately 200 lb of force every time it thrust its tail – 10 times more than Gray hypothesized – and at peak force can exert between 300 and 400 lb. [2]

Scientists determined that bottlenose dolphins found close to the shore off South Carolina and much of the east coast are a different species than those living in deeper water, according to a ...
It is the fastest mammal in the world and one of the fastest flying animals on level flight. Cheetah: 109.4–120.7 km/h (68.0–75.0 mph) [d] The cheetah can accelerate from 0 to 96.6 km/h (60.0 mph) in under three seconds, [58] though endurance is limited: most cheetahs run for only 60 seconds at a time.

NOAA Fisheries strongly urges mariners operating vessels 35-65 feet in length to transit at or under 10 knots within active seasonal management areas, in light of the danger posed to right whales ...
The pygmy right whale shares several characteristics with the right whales, with the exception of having a dorsal fin. Also, pygmy right whales' heads are no more than one quarter the size of their bodies, whereas the right whales' heads are about one-third the size of their bodies. [11] The pygmy right whale is the only extant member of its ...
