Net Dolphin

The Net Dolphin(망돌고래,mangdolgorae, net dol-whale, net dolphin) specialises in hunting. They gather fish for their queen the Net Dolphin Madame. They do this using their special ability to manipulate Shinsoo to create a net within the water. They use the net to transport the various aquatic animals directly to the queen's mouth. While they are doing this, they are hunted by Dogs and the Bull.

Notes and Trivia
Mangdol Whale is a mistranslation. "Mangdolgorae"(망돌고래): "mang" means "net", "dolgorae" means "dolphin". However, 고래(gorae) means whale. Dol(돌) means many things like "stone" and so on.

By adding dol(돌) to gorae(고래), the term "whale" becomes "dolphin"(dol-whale).

(Note from Tofu21: I don't know any Korean, I'm just using dictionaries and the like, to confirm. Yes, I can break down some of the hanja.)

This can be seen by the fact they all look like bottle-nosed dolphins, than whales.
