The blue sledodil split from the sea sledodil. It has become a large ocean predator, swimming after prey larger than anything they have swam after before. They haunt the oceans alone, often with strict territory rules. The youth swim the coasts and the adults inhabit the deeper areas with the bigger creatures. Each sledodil guards their own hunting waters viscously. Their diets change depending the biome, but the menu is often filled with the biggest animals in the vicinity. The jaws are big enough to finish most prey in one go, the blue sledodil ambushing from the depths and snapping their jaws around the neck or gut. strainbean are sometimes targets, although the giant shovelhead are far too big, and the Blues will go for the children and the sickly amongst them. Blue sledodil at the south pole are at war with the cetaplent, and have evolved into a stronger, tougher breed than the other ones north.
Blue sledodil reproduce every few years. Males, normally smaller than the females, will bravely invade a potential mates territory with food and court. Fertilized eggs will be taken to Somarinoa Coast by a mother and then laid around plantlife in vast amounts. At a similar time, other females will be coming to lay their eggs, so there will be enough to overwhelm predators and ensure the survival of a few. After they hatch they will have the color changing ability to hide and keep out of trouble, but they will loose this in favor of a deep and pale blue coating later in life. Only males will be able to flash their heads and tails to court with. The average life span of a blue sledodil is not very long, as each one is only seen as competition and a threat by another.
