What I did:
I searched up on what would happen if a grenade exploded underwater.

What I learned:
A grenade exploding underwater is far more dangerous than a grenade exploding on land.

Summary:
A grenade exploding underwater is far more dangerous as water is incompressible, so in an underwater explosion, it does the water does not absorb the pressure like air does, but moves with it. When the pressure wave hits your skin, it would hit the air-filled pockets of your body and instantly compressing the gases there, and probably resulting in ruptured lungs, blocked blood vessels and torn internal tissues.
