However, in scientific classification, it is still classified as a superfamily Porpoise rather than a Delphinidae. Pufferfish are larger than dolphins, and can grow up to 3 meters in length.

5. Are pufferfish, finless porpoise and white-fin dolphin a type of fish?

Not fish, they are mammals belonging to the genus Whale.

The finless porpoise, river dolphin, and white-fin dolphin are similar in appearance, about 1.5 to 10 meters long and weighing 50 to 7,000 kilograms. Females are usually larger than males. Most dolphins have distinctive head features. Due to the presence of lenticular fat, the forehead bulges in front of the beak, also known as the "frontal ridge". This structure helps to focus the sounds made by echolocation and foraging. Although some dolphins have frontal ridges, their beaks are short and the bulges of the forehead only outline a square appearance.

This type of small toothed whale is widely distributed in the world, but there is only one species in my country, the Yangtze River dolphin.

As an important economic fish resource, pufferfish has important reasonable development and utilization value. Pufferfish is delicious and has been a famous delicacy in the river since ancient times. Through artificial breeding of pufferfish, pufferfish can be deeply processed into various foods, thereby increasing the added value of pufferfish.

10. What are filter-feeding fish? What are filter-feeding fish?

Filter-feeding fish: A general term for a class of cold-blooded vertebrates that live in water all their lives, breathe with gills, use fins to assist body balance and movement, and feed on plankton. The most common types of filter-feeding fish are silver carp and bighead carp, two of the four major carps. Silver carp is a filter-feeding fish that mainly feeds on phytoplankton, while bighead carp is a filter-feeding fish that mainly feeds on zooplankton. Both types of fish are particularly suitable for breeding in northern waters, where they grow fast and are used in large quantities.
