Which national park has the most number of animals?

There isn't a simple answer to which national park has the "most" animals. Here's why:

* Different definitions of "animals": Do we mean total number of individuals, number of species, or something else?

* Difficult to count: It's incredibly challenging to accurately count all animals in a large park. Many are elusive, and populations fluctuate.

* Focus on specific animals: Parks often have a focus on certain species, making it hard to compare them across the board.

However, we can highlight some parks known for their incredible biodiversity:

* Yellowstone National Park (USA): Known for its large mammal populations, including wolves, bears, bison, elk, and more.

* Serengeti National Park (Tanzania): Famous for its annual Great Migration, with millions of wildebeest, zebra, and other herbivores.

* Amazon Rainforest (multiple countries): The most biodiverse place on Earth, with countless species of insects, birds, mammals, reptiles, and amphibians.

* Kruger National Park (South Africa): Boasts "The Big Five" (lion, elephant, rhino, leopard, and buffalo) and a vast array of other wildlife.

Ultimately, it's more about appreciating the incredible diversity of life in each national park than trying to quantify it with a single number.
