Detail of 10 Differences between a Dolphin and a Porpoise
Here is the detail of 10 differences between a dolphin and a porpoise:
Size:
Dolphins are generally larger than porpoises, with the largest species, the killer whale or orca, measuring up to 30 feet in length. Porpoises, on the other hand, are smaller, with the smallest species, the vaquita, measuring only up to 6 feet in length.
Appearance:
Dolphins and porpoises have distinct appearances that make it easy to tell them apart. Dolphins have a longer snout and a curved mouth, while porpoises have a shorter snout and a straight mouth. Dolphins also tend to have a more streamlined body, while porpoises are stockier.
Dorsal fin:
The dorsal fin of a dolphin is curved, while that of a porpoise is triangular. The dorsal fin of a dolphin is also usually more prominent and can be larger than that of a porpoise.
Teeth:
Dolphins have conical teeth, while porpoises have spade-shaped teeth. The teeth of dolphins are also more numerous than those of porpoises.
Color:
Dolphins are often brightly colored, with shades of blue, gray, and white. Some species of dolphins even have spots or stripes on their body. Porpoises, on the other hand, are usually a solid shade of gray.
Habitat:
Dolphins are found in both freshwater and saltwater, and they tend to prefer warmer waters. Porpoises, on the other hand, are primarily found in colder waters, such as the Arctic and Antarctic oceans.
Communication
Dolphins are known to be very vocal and communicate using a variety of clicks, whistles, and body language. They have a complex communication system that allows them to communicate with each other over long distances. Porpoises, on the other hand, are less vocal and rely more on body language to communicate.
Behavior
Dolphins are more playful and acrobatic than porpoises. They are often seen jumping and performing flips, and they are known to interact with boats and swimmers. Porpoises, on the other hand, are more reserved and tend to keep to themselves.
Lifespan
Dolphins have a longer lifespan than porpoises. Dolphins can live up to 50 years, while porpoises have a lifespan of around 20 years.
Species:
There are over 40 species of dolphins, while there are only six species of porpoises. Some of the most well-known dolphin species include the bottlenose dolphin, the spinner dolphin, and the common dolphin. Some of the most well-known porpoise species include the harbor porpoise and the Dall’s porpoise.
