Mediterranean whales are essentially rorquals ("skinny" whales): during the most intense period of industrial whaling (late 19th and early 20th centuries), right whales (cold-water whales, for their blubber) were the main target, so this activity had less impact on the Mediterranean basin. [9]
Common dolphin (swimming) 55–64 km/h (34–40 mph) [n] Common dolphins are the fastest marine mammals. When reaching their top speed, they take very short breaths. As an example, fin whales, which are much larger, can empty and refill their lungs in 2 seconds Tiger: 56–64 km/h (35–40 mph) [o]
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 ...
Oceanic dolphins or Delphinidae are a widely distributed family of dolphins that live in the sea.Close to forty extant species are recognised. 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).
Wholphins will also have mixed traits from their parents. They are mostly smaller in size compared to the false killer whales but larger than the bottlenose dolphins. Their coloring will be mostly a dark grey, with the body proportion and dental features falling between those of the two species.
Large whales tend to lobtail by positioning themselves vertically downwards into the water and then slapping the surface by bending the tail stock. Dolphins, however, tend to remain horizontal, either on their belly or their back, and make the slap via a jerky whole body movement. All species are likely to slap several times in a single session.
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]
The bottlenose dolphin is a toothed whale in the genus Tursiops.They are common, cosmopolitan members of the family Delphinidae, the family of oceanic dolphins. Molecular studies show the genus contains three species: the common bottlenose dolphin (Tursiops truncatus), the Indo-Pacific bottlenose dolphin (Tursiops aduncus), and Tamanend's bottlenose dolphin (Tursiops erebennus).
