Hide & Hold Out - H2o is a multiplayer survival game mostly based on PvP and social interactions, the action takes place in a post-cataclysm "waterworld" environment.
You can find many beasts by browsing the flooded lands.
Fishes, birds, marine molluscs... Most of them are harmless and can provide nourishment.
But some others can be very dangerous!
Getting too close to a shark or a jellyfish can be a death sentence for a player who isn't prepared.
That said,
there is currently no threatening animals above of the surface, at least... unless we add an alligator to the bestiary, right?
