Question

Is the shark a fish or a mammal?

Answer 1

Hint: Mammals are animals that belong to the class Mammalia. Mammals are one of the most developed vertebrate species in the animal kingdom. They have advanced qualities that distinguish them from all other animals. They are distinguished by the existence of mammary glands, which they use to feed their young. These are hairy, warm-blooded creatures with mammary glands to feed their offspring. They may be found all over the world and have adapted effectively to their environs, including oceans, deserts, and polar climates, as well as rainforests and rivers.

Complete answer:
Sharks are a type of fish. They are not mammals since they lack any of the characteristics that distinguish a mammal. They aren't warm-blooded, for example. Sharks are classified as fish, although their skeleton is constructed of cartilage, unlike that of most fish. Sharks are carnivores, which means they eat smaller fish. Sharks, on the other hand, are opportunistic feeders who will eat anything that can kill them.

Additional information:
Mammalia is the animal kingdom's largest class. They are divided into three subclasses based on how they reproduce: Eutheria, Metatheria, and Prototheria. This subclass of mammals gives birth to young. The young are created inside the mother and receive nutrients from the mother's placenta. Mammals in this subclass give birth to immature young, which remain in their mother's pouch until they reach adulthood. Marsupials and kangaroos, for example. The subclass Prototheria, sometimes known as Monotremes, is made up of egg-laying mammals. Echidna, for example, has a duck-billed platypus.

Note:
Warm-blooded animals that give birth to their young are known as mammals. They are the most common animal species found in practically all habitats. They have mammary glands, which aid in the production of milk to feed their young. A four-chambered heart is found in mammals. The renal portal system and the sinus venous system are both missing. Mammals can also lay eggs. They are referred to as viviparous.
