The Unknown Shark is a shark that lives in the waters off Sunset Beach. Its exact species is unknown, but his appearance looks similar to that of a Great White due to its size.
- The shark lives fairly close to shore, as he attacked Broseph when he was surfing the Duke board.
- He also resembles a more-designed Shark from the Total Drama series.
- The shark also has friends seen in "O Broseph, Where Art Thou?"; at least two others.
- The shark is a Great White Shark (Carcharodon caracharias)
- When the shark ate Emma's fish, the angle of attack was exactly the same as in Jaws, which featured a killer Great White shark in the 1975 movie of the same name.
