Dunkleosteus (meaning “Dunkle’s Bone”) in real life had the fastest bite of ANY animal in history, able open AND close its mouth in 1/50 OF A SECOND!! This causes water to be pulled in so quickly, it’s mouth then acted as a split-second vacuum, instantly pulling its prey into its mouth.
Oh, and it ate sharks during its time (late Devonian Period) since sharks weren’t as apex or as developed (looking more like eels, ie. the Cladasolache).
Alright so if you know where the green pillar is go to the right side right into the water keep going deeper until you find a lot of rocks (there’s a lot of rocks there so if you can’t find rocks there meaning you’re in the wrong spot or something) it’s a little hard to search that spot because of the rock but there are a lot of didn’t things like eels and dunkleosteus and those water things that you can build a base well I found some anyway be on a ichthy
They may seem calm, and won't be dangerous most of the time, but don't be fooled: They boast descent damage and godlike resistance, think of them as Rock Elementals of the sea, exchanging HP for numbers.
Just like elementals, they have a small aggro range, very slow movement speed and not the highest of the DPS. But if you get cornered, be ready to suffer a slow death by their stone-crushing jaws.
On the center make dunkleosteus quite the pest when trying to gather silica pearls or other deep water resources. If one is provoked by combat or getting too close other dunkleosteus will come to attack you from very far away and it is almost impossible to escape once they swarm you or your tame.
