Creative Ideas for Sharks

Do you know the game Hytale game? This game seems to be a competitor of Minecraft, it is being developed by a group of people involved in the Minecraft Modding community!

Naturally, they made sharks just like the generic aggressive monstrous enemy with no depth whatsoever, so I decided to contribute some ideas of creatures to the oceans of Hytale!

In some of these ideas, I explored fantasy abstractions of tonic immobility and electro-sense, characteristics of sharks that I never saw being explored creatively. I have no idea if the developers will care about my ideas, but at least I tried!
