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).
I’ve made the comment on this having the fastest bite of all time, and I thank you for correcting me with this information. I actually never heard about this ant, so major thanks for this break in the case. And sorry about what I said before with this creature.
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.
