It would be located all the way at the right side of the map. It would contain blue jellyfish. Going deeper reveals green, then pink. It would be a disaster for beginners, but a feeding zone for high levels.

There are also many artifacts and mission shells here. You can also gain pirate gear that you equip on your shark instead of buying them in the shop.
Hazards : Few toxic barrels, but tons of mines. Great white and hammerheads spawn here. Various fish spawn inside and outside of the ship.
The ship should only appear if you are a Tiger Shark Level 9 or above, or else the space where the ship is supposed to be is not there. Once you reach Level 9 there is also a sign on the beach saying " Cruiser Ship Missing! " also.
on the far right of the map there is blue,green and pink jellyfish in an area,but i guess you are meaning something on a bigger scale.Oh i do agree about the boss part,it should also be like the giant crab boss that you have to do many attacks before defeating it,unlike the enemy big daddy where you can gobble it up in a sec with another big daddy or better.Oh the boss should also give gems.
