Wailord is a huge Pokémon based on the blue whale. It has small beady eyes, a huge mouth, and a throat that is lined with grooves. It has a blue back with and four white spots, two breathing nostrils on top of its back, and a tan, grooved underbelly. It has two pairs of fins along its sides and a horizontal tail at the back.
When it is jumping out of the water, it makes a giant splash due to its large size. It can create shockwaves by breaching and crashing onto the water, which can knock out the opponents. It can dive deep at 10,000 feet (3,000 meters) in one breath. It lives in the sea in large groups called pods. A pod of Wailord travels together in order to search for food and is able to eat large quantities at one time, such as schools of Wishiwashi. However it will flee from Wishiwashi when it becomes its School form. When a Wailmer is attacked by its predators Sharpedo or Dhelmise, its whole pod works to defend it. Wailord is popular due to its immense size. As a result, Wailord-watching is a favorite sightseeing activity in various parts of the world. However, they are known to be driven away by fishermen, so they don't eat too much fish Pokémon.
