Krokesia

A subspecies of roper which appears in gloomy areas. Since it moves in the dark, its senses are particularly sharp compared to other ropers. In particular, the tentacles extending from its body is able to sense changes in airflow, thus allowing it to notice the slightest of movements, even those of a mouse, a distance away. They also have an organ that resembles an eye, but it seems as if they can't see very well with it.
