Segacedi is a sewer shark that can be found under the Black Market in the Underbelly of Dalaran. One could, if so desired, "jump the shark". Oddly, you cannot loot this shark.
During the Purge of Dalaran, Sorin Magehand is levitating a Sunreaver citizen over Segacedi, and when engaged drops him onto the shark to be devoured.
Trivia[]
This seemingly random shark in Dalaran's sewers is a reference to the game Sewer Shark for the Sega CD.
