The Sea Guardians: Sharks

I suggest adding sharks to Minecraft as neutral ocean mobs. Sharks would normally swim peacefully and attack players only when attacked first. Players could feed sharks their favorite fish to build trust. A trusted shark would remain a wild animal rather than becoming a normal pet, but it could protect the player underwater by attacking hostile mobs such as Drowned. This would give sharks a unique gameplay purpose, make ocean exploration more interesting, and encourage players to interact with marine wildlife.
