Add Whales to Minecraft - The Peaceful Giants of the Sea

It would be a great idea for Mojang to add whales to Minecraft. Whales would greatly add to the mystical and mysterious environment of the Minecraft oceans. Adding a larger mob to Minecraft would give more variety to the list of mobs. Whales would be large, slow moving, and graceful mobs. To account for their large scale they will spawn in Deep Oceans. The depth of deep ocean should also be increased. Whales would be peaceful, they would not drop anything, they would not be able to be leaded, and would not be able to be breed by a player. 

Please take my ideas into consideration, thank you.
