Mission Shells were shells scattered through out the map. Upon the discovery of a shell, a mission will be unlocked, making it available for completion and revealing what you must do to complete the missions. Missions are tasks which are assigned to all sharks in Hungry Shark Evolution. These missions give rewards of coins when completed when unlocked, with the exception of the Top Secret Lab Sharks, whose missions give gems.
A Super Mission is unlocked for each shark when all previous missions have been completed. The Super Mission yields the greatest reward of all missions for that shark, generally more than triple the amount. Every super mission requires you to achieve a certain amount of points in one run.
The bigger/later obtained the shark, the harder the missions (with the exception of Sharkjira, whose missions are very easy).
There are a total of 117 missions assigned to non-special sharks: 104 normal missions, and 13 super missions. There are 40 missions assigned to Special Sharks: 32 standard missions, and 8 super missions. Missions are tasks of varying but unspecified levels of difficulty that yield increasing number of coins depending on the shark it is assigned, and the difficulty. You must complete a mission in one game - not overall. Also, rewards for missions for a specific shark may be different. Note that gems cannot be rewarded (for standard sharks).
Each shark has 9 missions (except for the Top-Secret Lab Sharks which have 5). Completing a mission rewards coins. Completing 50 missions unlocks the Jet pack for free use, and 75 will unlock the Missile Launcher. Later the mission shells were removed in the Kraken update, there are just missions.
