Salam Sobat Penurut, Let’s Discover The Truth About Dolphins!

Dolphins are one of the most fascinating creatures in the world. They are known for their intelligence, agility, and playful behavior. However, despite their many similarities to fish, they are not actually fish. In fact, dolphins are mammals, just like humans. But what makes them mammals? In this article, we will explore the various types of evidence that show why dolphins are mammals and not fish.

What Makes Dolphins Mammals?

Before we dive into the evidence, let’s first understand what makes a mammal a mammal. Mammals are a class of vertebrate animals that are characterized by their ability to nurse their young with milk produced by mammary glands. They also have hair or fur, a four-chambered heart, and a diaphragm for breathing. Mammals are further classified into various orders, with dolphins belonging to the order Cetacea, which includes whales and porpoises.

Evidence #1: Reproduction

One of the most significant pieces of evidence that dolphins are mammals is their method of reproduction. Dolphins give birth to live young, which is a characteristic of all mammals. Fish, on the other hand, lay eggs to reproduce. Dolphins carry their young in their womb for up to 12 months, and when the calf is born, it is fully developed and able to swim and breathe on its own.

Evidence #2: Breathing

Another piece of evidence that dolphins are mammals is their method of breathing. Dolphins have lungs and breathe air, just like humans. They must come to the surface of the water to breathe, and they do this by expelling air from their blowhole, which is located on top of their head. Fish, on the other hand, breathe through gills, which extract oxygen from the water.

Evidence #3: Body Temperature

Another characteristic that sets dolphins apart from fish is their ability to regulate their body temperature. Dolphins are warm-blooded, which means they can maintain a constant body temperature, regardless of the water temperature. Fish, on the other hand, are cold-blooded, which means their body temperature is determined by the temperature of the water around them.

Evidence #4: Milk Production

As mentioned earlier, mammals are characterized by their ability to nurse their young with milk produced by mammary glands. Dolphins are no exception. Female dolphins produce milk to feed their young, just like humans. This is another piece of evidence that shows why dolphins are mammals and not fish.

Evidence #5: Skeleton

The skeletal structure of dolphins is another piece of evidence that shows why they are mammals and not fish. Dolphins have a skeleton that is similar to other mammals, with a backbone, ribcage, and skull. Fish, on the other hand, have a simpler skeletal structure that is made up of cartilage or bone.

Evidence #6: Brain Structure

Dolphins are known for their intelligence, and this is reflected in their brain structure. Like other mammals, dolphins have a complex brain that is capable of advanced cognitive abilities, such as problem-solving and communication. Fish, on the other hand, have a much simpler brain structure.

Evidence #7: Taxonomy

Finally, the taxonomy of dolphins is another piece of evidence that shows why they are mammals and not fish. Dolphins are classified as part of the order Cetacea, which includes whales and porpoises. This order is part of the class Mammalia, which includes all mammals. Fish, on the other hand, belong to the class Osteichthyes, which includes all bony fish.
