Are dolphins fish? Are dolphins fish

Haven't you ever taken a biology class?

Dolphins are not fish.

The way fish reproduce oviparously is not the way dolphins reproduce, as a mammal, dolphins adopt a viviparous way of reproduction. Dolphins have a relatively long gestation period, similar to that of humans, and sometimes even longer than human gestation. After the gestation period, the dolphin will give birth to the baby dolphin directly, and the tail of the baby dolphin will be exposed first, unlike humans, who come out first.

After that, it will go through the process of breastfeeding. The baby dolphin spends a lot of time with its mother, and in the process, the other dolphins in the group will also protect the newborn dolphin.

No, dolphins belong to the mammals.

Dolphins are a common name for aquatic mammals, mostly small toothed whales, which live widely in the world's oceans, and are also found in brackish water near inland seas and river estuaries, and are occasionally seen in inland rivers. Usually like to live in groups, preying on fish dry sedan chairs, squid, etc.

The dolphin family evolved from the late Oligocene more than 20 million years ago, and there are about 17 genera and 37 species, which is the largest family of cetaceans, and black cetaceans such as pilot whales and killer whales also belong to this family, which are essentially large dolphins.

A dolphin is not a fish, it just looks like a fish. Dolphins are a collective term for a group of small and medium-sized toothed whales, which are aquatic mammals. It belongs to the class Mammals, Cetaceans, the suborder of ulnar keytooth whales, and the general family of dolphins (now classified as mammalian steel, artiodactyls, sub-whale large trap group, toothed whale order, and dolphin family), with 17 genera and nearly 40 species, which is the largest family of cetaceans.

Dolphins are small to medium-sized cetaceans. The body length is about meters, and the weight is 30 14000 kg. Males are usually larger than females.

Most dolphins have a prominent head feature with a raised forehead before the beak, also known as a frontal bulge, due to the presence of lenticular fat, which helps to gather echolocation and foraging sounds. Dolphins swim fast, usually at a maximum speed of about 30 to 40 km per hour, and some species of dolphins can reach speeds of more than 55 km per hour and can maintain a long time, making them the champion of long-distance swimming in the ocean.

Dolphins mainly inhabit the warm waters of the tropics, but there are some species such as the right spinal dolphin that prefer cold waters. Usually lives in shallow water or at least stays near the surface of the sea. It is distributed in all seas of the world, with tropical coasts being the most abundant, and some freshwater rivers are also found.

Dolphins do not belong to fish, but are mammals.

Dolphins are small to medium-sized cetaceans with a body length of about 14,000 kilograms. Males are usually larger than females. Most dolphins have a prominent head feature with a raised forehead before the beak, also known as a frontal bulge, due to the presence of lenticular fat, which helps to gather echolocation and foraging sounds.

Some dolphins have a forehead but a short beak and a raised forehead that outlines only a square appearance. Most dolphins have a sleek, sleek body shape with a hook-like dorsal fin (other forms are also present). Some dolphins have eye-catching colourful patterns on their bodies, while others are more drab colours.

Habits: Dolphins swim fast, usually the fastest speed is about 30 40km per hour, some species of dolphins can exceed 55km per hour, and can maintain a long time, is the champion of long-distance swimming in the ocean.

Some dolphins are highly social species, live in large groups, and exhibit many interesting group behaviors. There are many ways to cooperate within a group, one example is that dolphins in a group sometimes attack sharks and kill them by impact. Members also work together to help injured or sick individuals.

Pods of dolphins often follow the boat to ride the waves, sometimes acrobatically taking to the skies, a spectacular sight.

They feed mainly on fish and squid, with killer whales also preying on other cetaceans and pinnipeds. Like other toothed whales, dolphins rely on echolocation for predation and can even stun prey with loud pitches.
