Why can't whales survive in a pond?

Whales cannot survive in a pond primarily due to their size and the limited space. Most ponds are too small to provide the necessary depth and room for whales to swim freely and dive, which is essential for their physical and social behaviors. Additionally, the water temperature and quality in a pond may not be suitable for whales, which require large volumes of water to regulate their body temperature and maintain their health. Finally, ponds often lack the abundant food sources available in the ocean, making it difficult for whales to meet their dietary needs.
