The difference between dolphins and porpoises is clear in that members of this family have small flippers, lack the prominent beak associated with many dolphins and have a more triangular dorsal fin rather than falcate. Some dolphins are even opportunistic scavengers who will follow fishing boats and whales to feed on discarded fish. Knowing the difference between the two kinds of animals will help you distinguish them from one another and remember how they ought to be treated. You can use your new taxonomic knowledge to help protect dolphins and porpoises—if you see one stranded on the beach, you can report it to NOAA here. These behaviors serve important […], Hematopoietic cell transplantation (HCT – formerly termed “bone marrow transplantation”) is an established treatment for patients with life-threatening hematological and […], The horse-chestnut leaf miner, Cameraria ohridella (Lepidoptera, Gracillariidae), is a major pest of horse-chestnut trees (Aesculus hippocastanum) in Europe. The easiest way to tell dolphins and porpoises apart is that porpoises dont have narrow snouts like dolphins do. 1) There are 6 species of porpoises, all of which are found in oceans.

Can We Use Entomopathogenic Fungi As Endophytes For Biological Control Of The Horse-Chestnut Leaf Miner? Dolphins are much more diverse than porpoises, as there are around 32 different species of dolphins. Learn all about Britain's dolphins, porpoise and whales – including identification, the best places to see them and boat excursions – with our guide to the UK's most common cetacean species. Dolphins have a more hooked shape dorsal fin (it resembles the shape of a wave), while porpoises have a more triangle shaped dorsal fin. Dolphins have a curved, or hooked, fin, while porpoises are equipped with a triangular one, NOAA says. Dolphins are much sleeker and more aerodynamic looking than porpoises. Share . A Curved Fin Means It’s a Dolphin. However there are three main differences between dolphins and porpoises, that is, porpoises are divided in to six species and sub species, while dolphins are divided into 40 different main types, the average dolphin is generally longer than the average porpoise, and the most obvious visible difference between the two groups is that porpoises have flattened, spade-shaped teeth. More differences between dolphins and porpoises are discussed in this article. There is a prominent difference in the dorsal fins of these 2 mammals. As you may know, dolphins, porpoises, whales and orcas belong to the order Cetacea (from Ancient Greek kêtos, “sea-monster or huge fish”). Dolphins and porpoises belong to the same scientific order, Cetacea. Porpoises are generally smaller than dolphins. Dolphins have pointed, canine-like teeth, whereas porpoises have flat incisor-like teeth. Msg & data rates may apply. Dolphin vs Porpoise. We learn from each other and assist one another on our awakening journey.” — Edward Mills. There are 32 living species of dolphins and only six species of porpoises. Although not many people know it but there are various different types of dolphins and many cetacean creatures that resemble dolphins but are not at all dolphins. They don’t vocalize to communicate with other porpoises as often, a result of their more solitary lifestyle. Porpoises don't have the pronounced beak that most, but not all dolphins have and they also have different shaped teeth. Female porpoises usually have a gestation period of around ten and a half months, and usually, birth only one calf at a time. A related family to dolphins are Porpoises. Dolphins also tend to have a longer rostrum (the pointy ‘beak’ part of their face), while porpoises have a much shorter one, although there are definitely a few exceptions this this rule (including the non-existant rostrum of the Risso’s dolphin!). But the main difference between the two lies with their appearance. Science Trends is a popular source of science news and education around the world. On the other hand, there are 40 species of dolphins, of which 5 are exclusively found in freshwater. A young dolphin calf will stay with its mother, nursing for between 11 months to 2 years. How many people know that dolphins and porpoises are different species? Please try 2) Porpoises are smaller, but stouter than dolphins. Dolphins tend to be leaner, with a longer, streamlined shape. Dolphins are quite noisy, making a variety of clicking, squeaking and squawking noises. Porpoises are generally smaller than dolphins. Porpoises track down small groups of fish, octopus, squid, and crustaceans to eat. The porpoise ear has specific adaptations to the marine environment. Dolphins are also often longer, averaging about six to 12 feet in length, where porpoises only reach a maximum seven feet in length. Habitats. Dolphins sport longer snouts, bigger mouths, more curved dorsal fins, and longer, leaner bodies than porpoises. Dolphins have a curved, or hooked, fin, while porpoises are equipped with a triangular one, NOAA says. Here are 5 key differences between dolphins and porpoises. English. By observing the morphology of teeth, porpoises and dolphins can be clearly distinguished. The dorsal fin can also give clues about the difference between the two–dolphins have a curved dorsal fin, while the porpoise fin is strictly triangular. Porpoises also tend to be more wary of humans, avoiding them. First of all with around 40 known species of dolphin there is a much greater diversity within the dolphin family as compared to the 6 species of known porpoise. Sign up for our science newsletter! Prove you're human, which is bigger, 2 or 8? Porpoises also have different teeth; they are spade-shaped and look much more like our teeth, whereas dolphins have cone-shaped teeth (which looks like an upside-down ice-cream cone). The main differences between porpoises and dolphins are anatomical, as mentioned earlier. This lists the logos of programs or partners of NG Education which have provided or contributed the content on this page. "Generally speaking, dolphin bodies are leaner, and porpoises' are portly," according to NOAA. 1. Porpoise vs. Dolphin. The easiest way to tell dolphins and porpoises apart is that porpoises don’t have narrow snouts like dolphins do. One difference: Dolphins and porpoises have about the same color pattern, but dolphins can grow to 12 feet in length while porpoises are typically a few feet shorter. Porpoise teeth are spade-shaped whilst dolphins are conical.
