* Water: The majority of their body is water, just like humans. This helps with temperature regulation, nutrient transport, and many other essential bodily functions.
* Proteins: These are the building blocks of their muscles, organs, skin, and other tissues.
* Fats: Dolphins have a layer of blubber for insulation in cold waters. Fats are also important for energy storage.
* Carbohydrates: These provide energy for their active lifestyle.
* Minerals: These are essential for various bodily functions, including bone health, muscle contractions, and nerve transmission.
* Vitamins: These help with a variety of bodily processes and are obtained through their diet.
Specifically, their bodies are composed of:
* Skin: Their skin is smooth and streamlined, helping them move through the water efficiently.
* Muscles: Dolphins have powerful muscles for swimming, jumping, and hunting.
* Bones: Their bones are lightweight and strong, designed for efficient movement in the water.
* Organs: They have all the same organs as other mammals, including a heart, lungs, brain, stomach, intestines, etc.
* Blubber: A thick layer of blubber provides insulation and energy storage.
They are NOT made of:
* Plastic: Unfortunately, marine animals like dolphins are often affected by plastic pollution, but they are not composed of it.
* Any other materials not found in the natural world: Dolphins are entirely biological organisms.
