Top best answers to the question «How are porpoises different from baleen whales and whales»
- Porpoises possess very flat and tiny teeth, while dolphins have large, conical teeth. The last major difference between the two has to do with the number of blow hole openings, porpoises having two nostrils like baleen whales and dolphins having one nostril like the toothed whales.

Pioneering biologist Dale Rice was the first to document the whales' presence in the Gulf of Mexico, and the NOAA researchers who confirmed the species are naming it Balaenoptera ricei, or “Rice's whales,” in his honor. Rice died in 2017 after a six-decade career.

Instead of teeth, they have long horny plates edged with bristle-like fibres that strain small marine animals from seawater. The other group includes the toothed whales or Odontocetes, with around 72 species including the beaked whales, killer whales, pilot whales, dolphins and porpoises.
There are several differences between their blowholes. Baleen whales have two blowholes, while the toothed whales, and subsequently dolphins and porpoises only have one. The structure of dolphin blowholes is also different from both whales and porpoises, which allows them to make a variety of whistle sounds to communicate with others.
Baleen whales have baleen plates in their mouths instead of teeth which allow them to filter feed. Their baleen, also known as whalebone, is not made of bone at all. It is made of keratin similar to our fingernails and grows downwards from the upper jaw of most large whales. When baleen whales open their mouths, water and prey, such as krill or small fish upon which they feed, pour in.
Toothed whales, including dolphins and porpoises, are usually smaller than baleen whales and have one blowhole. T oothed whales are selective eaters and often hunt down individual animals, such as fish, squid, seals or sea lions.
Dolphins and porpoises all have teeth and rather confusingly are known as ‘toothed whales’ too! Another obvious difference between baleen and toothed whales is the number of blowholes on top of their head; baleen whales have two whereas toothed whales have one.

- Bottlenose Dolphins are very different from their Harbouse Porpoise cousins. They will often fully breach the water giving great displays. They are a very curious and intelligent mammals. Moreover they will often approach boats to check them and their occupants and will, when playful travel in the boats wake.
- Recently discovered hybrids between male harbour porpoises and female Dall's porpoises indicate the two species may actually be members of the same genus. Porpoises have a bulbous head, no external ear flaps, a non-flexible neck, a torpedo shaped body, limbs modified into flippers, and a tail fin.
- The whales differed from all of their congeners by having the following unique characters: a substantially smaller body size of physically mature individuals, proportionately shorter beak, and darker body colour. Thus, we conclude that the whales are a third Berardius species.
The beaked whale family is the biggest of the large toothed whale families with 22 members - this is likely to increase as scientists learn more about these squid-eating, deep water, mysterious whales.Are fin whales toothed or baleen?
Examples of baleen whales include the blue whale, right whale, fin whale, and humpback whale.Are killer whales baleen or toothed?
Killer whales are a type of dolphin, a group of specialized toothed whales. Lance Barrett/Courtesy of NOAA Learn more about the diversity of these marine mammals in Whales: Giants of the Deep, which opens at the Museum Saturday, March 23.Do right whales have baleen plates?
- Right whales have enormous heads which are about one-third of the total body length. Inside their mouths are hundreds of baleen plates, each up to 3m (8ft) in length. Their jaws are strongly arched to accommodate their baleen.
Baleen whales can be found in all oceans worldwide, from polar seas to temperate and tropical zones. Some species of baleen whales have limited distribution.Are porpoises and dolphins whales?
Dolphins, porpoises, and whales all belong to a group of marine animals known as cetaceans. Like all mammals, cetaceans are warm-blooded, breathe air, and suckle their young.Are porpoises dolphins or whales?
Porpoises are often confused with being the same animals as dolphins, but the two groups of marine mammals maintain significant differences. Porpoises are shorter, stockier animals with flat faces, as opposed to the curved beak of dolphins. Porpoises have two blow holes, whereas dolphins have one.How are whales different from dolphins?
The two animals are physiologically different, with whales often being larger than dolphins ...How are whales different from fish?
Whales are warm blooded. Fish are cold blooded. Whales breathe air through lungs. Fish use gills to extract air from water.What makes whales different from fish?
What makes whales different from fish? Fish have gills that extract oxygen from the water and allow it to live underwater their entire lives. On the other hand, whales do not have gills but instead have one or two blowholes that connect to their lungs, which allow the whale to breathe in air.Which is more numerous baleen whales or toothed whales?
- Toothed whale species are much more numerous than baleen whale species. The number of teeth of which varies from one species to another. Certain species of dolphins have over 160 teeth; in some species of beaked whales, however, the teeth of females will never develop to protrude out of the gums.
- Unlike other species of baleen whale the bowhead whale is known as a skimmer. Rather than engulfing a large group of prey in a single gulp these marine mammals will continuously keep their mouth open while swimming forward in order to skim the water and filter the prey that enters its mouth and gets caught in its bristles.
Their coloration is very dark gray or black with contrasting white markings on the dorsal fin and tail that distinguish Dall’s porpoises from other cetaceans. All-black (melanistic) and all-white (albino) forms also exist but are considered rare.What makes a dall's porpoise different from other porpoises?
- Dall's porpoise can be differentiated from dolphins and other porpoises by the distinct rooster tail of spray their dorsal fin makes at the surface of the water when travelling at high speeds.
Porpoises have spade-shaped teeth, stubby faces, and triangular dorsal fins. Of the two families, dolphins have greater diversity. There are 32 living species of dolphins and only six species of porpoises. Dolphins range in size the 5.6-foot Maui’s dolphin to the 31-foot orca, which is the largest dolphin. Yes, orcas are dolphins!What is the difference between baleen whales and toothed whales?
- Baleen whales are generally larger than toothed whales except for the sperm whale which is very big and has teeth. Many baleen whales migrate annually, travelling long distances between cold water feeding areas and warm water breeding areas.
- Bearing a strong similarity to pygmy killer whales, melon-headed whales can be told apart by their flippers which are much more sharply pointed, and their heads which are more triangular. As well as pygmy killer whales, melon-headed whales can also be confused with false killer whales.
- Unlike toothed whales, baleen whales do not have wax ester deposits nor branched fatty chain acids in their blubber. Thus, more recent evolution of these complex blubber traits occurred after baleen whales and toothed whales split, and only in the toothed whale lineage.
