Sea ghost

This species has changed a lot since it was forced to abandon Earth and continue to strike terror 11,000 metres deep, with all the difficulties this presents. As the darkness at this depth is all-consuming, scaring others from behind soon ceased to work; not to mention the white sheet, which at these temperatures had to be replaced by a thick blanket; or the shackles, which restrict its movements. But, thanks to its ability to adapt, little by little these specimens were able to demonstrate their inexhaustible talent: they began by raising the alarm about a supposed warming of the waters, continuing with the presence of objects on the seabed and finally with sightings of unidentified ships of humanoid beings. Terrifying, isn’t it?
