* They are mammals. This means they give birth to live young, nurse their offspring with milk, and have hair or fur (even though whales have very little).
* They are herbivores. This means their diet consists primarily of plants.
* They are large animals. While there are exceptions within these species, cows, elephants, and whales are generally considered large compared to other animals.
Here's a breakdown of what makes each animal unique:
* Cows are ruminants, meaning they have a multi-chambered stomach and chew cud.
* Elephants are the largest land mammals and are known for their intelligence and social behavior.
* Whales are the largest animals on Earth and are adapted for life in the ocean.
While they share some similarities, these three animals are quite different in many ways.
