Bulky Hammerhead

Splitting from its ancestor, the larger bulky hammerhead has flourished within the warm waters off of Darwin and Drake. Taking towards a more carnivorous diet, bulky hammerheads feed on just about anything smaller than them and will swarm fresh corpses within hours once they sense them. Unlike its ancestor, this species has not only lost their ability to photosynthesize but has also evolved gills, with fleshy entrance - rich in blood vessels - at the front of their heads and exit "slits" running down their backs. Their 4th pair of legs, while primitive projections in their ancestors, have become fully functioning. They have also evolved a third, crest-like horn that contains photosensitive cells that alert them when something swims/moves over them. These cells also exist within their twin tail-like projections, thus allowing them to know when they are hidden or if something should attempt to come at them from behind.

Several times a year, males and females will release their gametes into the water. The resulting larvae make their way into the plankton, eating smaller swarmers while attempting to avoid larger predators. After roughly two months, they sink towards the sea floor, where they will remain for the rest of their lives. This typically lasts anywhere from three to four years should they manage to avoid predation and the like, though they will become sexually mature a year's time.
