Dunkleosteus

General Background
Dunkleosteus is an arthrodire placoderm which lived during the Late Devonian and is estimated to have reached lengths up to a maximum of 33 feet or 10 meters. It has an estimated bite force of approximately two metric tons which would of been used to kill and eat smaller placoderms and soft-bodied organisms.These fish had no teeth,instead they had tooth like plates that were sharpen by rubbing against each other.If a shark bit you in the middle,you would have a little serration.If Dunkleosteus bite you,it would cut you in half.These fish once ruled as 9(possibly 10)species all over North America,Europe and Africa.Their extinction was actually part of a mass extinction in the Late Devonian that wiped out the placoderms and nearly prevented vertebrates from conquering the land.

Abilities
Dunkleosteus has three abilities, a bite, a sped bite, and a toggled gait ability.

Bite - A simple bite that most animals have.

Sped Bite - A bite that when done allows the Dunkleosteus to go to a speed of 30 and deal damage.

Gait - A toggling of speed to switch between 20 and 10 speed.

Intended Playstyle
Dunkleosteus is intended to be a slow moving ambushing predator with a slow metabolism. It is intended to use its "Sped Bite" to quickly gain speed to catch up with a prey item. Its coloration matches the depths of the Devonian in which it can camouflage in and hide at the bottom. Aside from this, it is intended to easily be capable of fighting Titanichthys and other smaller placoderms, including younger individuals of its own species. Its coloration and shape resembles that of the previously mentioned Titanichthys so that it can be confused with a non-threatening filter feeder. The main differences between the two are that Dunkleosteus has more tooth plates which are much larger and a thicker lower jaw. Along with this, Dunkleosteus possesses a dimmer underside and brighter eyes.
