Gilgoblins are an offshot of the Goblin race from Warcraft, exclusive to World Of Warcraft as part of the Cataclysm expansion they are a semi-aquatic version of regular Goblins who have fish-like adaptations not unlike small sharks.

The mutation that has allowed them to survive the ocean depths has also apparently robbed them of the infamous scheming mindset most Goblins have, replaced instead with an instinctual and chaotic greed that sees them try and murder anyone nearby in order to steal their goods.
