Potential New Shark Pokémon Inspirations
Given that the only current confirmed Shark Pokémon are Sharpedo and the Garchomp line (which are Landsharks), Winds and Waves are a chance to introduce one or more new Shark Pokémon. And there are quite a few choices to choose from.
There are 3 species of Reef sharks in Indonesia: The Blacktip Reef Shark, the Whitetip Reef Shark, and the Gray Reef Shark.
There is also the Indonesian Whaler Shark- which actually doesn't seem to hunt whales and is more akin to a whale shark, because it is a species of shark called a Requiem shark
There are also a few unique reef-dwelling shark species to tap into:
The Bamboo Sharks- bottom-dwelling sharks that hunt for crustaceans and small fish in the sand on the floor of the reef
Wobbegong Sharks- which are a type of Carpet Shark, which means they have very flat bodies they use to aid in camouflaging themselves in the environment on the floor of the reef
Walking Sharks- a type of shark that uses its fins to "walk" along the reef's floor and coral flats
Any one of these families of sharks could make for some interesting new Pokémon to meet in the new region.
