This Minecraft modification will add new items and aquatic mobs to the oceans of minecraft!!

Sponge
Sponge is found on the bottom of the ocean.
If you kill one, it drops 5-10 sponges and when you craft 9 sponges,(In the same way that you craft iron ingots into an iron block) you will get a sponge block
It can be brewed with inc sacs to create a potion of waterbreathing.
Sharks
Sharks are an aggressive mob with 25 health bars.They drop raw shark meat and shark bones. Shark bones have he same uses as regular bones dropped by skeletons. Raw shark meat heals 2 1/2 hunger bars but when cooked into shark meat , it restores 5 hunger bars. Killing a shark gives an average of 5 experience.
Sharks only spawn on the bottom of the ocean.

Crab
Crabs are a passive mob but will attack if provoked (Like an enderman). They drop raw crab meat. Raw crab meat heals 2 hearts but when it is cooked, it heals 4 hunger bars.Killing a crab will give an average of 2 experience.
Crabs only spawn on beaches but can sometimes be seen roaming around other biomes.

Turtle
Turtles are a passive mob and can be seen swimming around in water sometimes. They drop turtle shells. Turtle shells can be sold to villagers. When you attack a turtle, it will hide in it's shell and will come out once it thinks it is safe. Turtles will give an average of 2 experience.

Seagulls
Seagulls are a passive mob and are found by land. If you are lost out at sea , it is a good idea to follow a seagull because they will always go to land after atleast 3 minutes. Seagulls drop feathers and are good for bow practice because you can find them flying around. If you run up to them on land, they will fly away.
Seagulls give an average of 4 experience. The reason they give more experience is because they are tough to shoot out of the air.
