Whales are the largest mammals in existence, and their size is "beyond imagination".

The largest whale, the blue whale, can reach a length of 30 meters, equivalent to three buses connected at the beginning and end.

Their weight is amazing, the largest blue whale can weigh up to 180 tons, which is 25 times more than an elephant!

As a social animal, whales are very interesting in their habits.

1. Singer. Whales have wonderful singing voices and are the most outstanding singers in nature. They sing to communicate and courtship and their songs are like a unique "whale language".

Interestingly, researchers have found that the whale's song changes over time, as if in pursuit of fashion trends.

2. Jumping. Whales love to perform jumps. When they leap from the surface and then land heavily, they create a huge splash of water.

This performance is called a whale leap and is one way for whales to show their strength and also a way to communicate.

3. Water spouting. Whales breathe through their nostrils (located on top of their heads) and each time they breathe they spurt out water vapor from the air, creating a spectacular column of water.

Although whales are the top predators in the ocean, they face many challenges as well.

1. The whaling industry. In the past, the whaling industry was prevalent, leading to a sharp decline in many whale populations.

Although whaling is now banned in many countries and regions, some countries and regions continue to hunt whales.

2. Ocean pollution. Ocean pollution has a serious impact on whales. Plastic garbage and chemical pollutants can affect the living environment and food sources of whales, and even endanger the lives of whales.

3. Climate change. Global climate change has led to changes in the marine ecosystem, which has a considerable impact on the survival of whales.

Phenomena such as rising ocean temperatures and melting polar ice caps may lead to changes in the whales' habitat and food sources, thus affecting their survival.

What can we do for the whales?

As inhabitants of the Earth, we have a responsibility to protect whales, the beautiful creatures of the sea. So, what should we do?

1. Support marine conservation organizations. Support organizations that work to protect marine life, such as the World Wildlife Fund (WWF), Sea Shepherd (Sea Shepherd), etc.

2. Reduce the use of plastic products. Minimize the use of single-use plastic products, such as plastic bags and bottles, which will eventually enter the ocean and pose a threat to marine life, such as whales.

3. Promote the concept of environmental protection. By promoting the concept of environmental protection, more people can understand the importance of ocean protection, thus enhancing people's awareness of environmental protection and reducing the pollution of the ocean.

Whales are one of the most mysterious creatures on earth. We are fascinated by their huge size, beautiful songs, and unique living habits.

At the same time, we should pay attention to the challenges faced by whales and do what we can to protect these mysterious and beautiful creatures.
