"2007 - Monster 3" by Kent Jensen

A ruthless carnivore, I really like this one for it's unique design and it's ruthless carnivore traits.

The grellken comes from a planet with a gravity below 1G, which explains why the wings and limbs looks too small to carry the creature. It's head is covered with a light sensitive membrane functioning like an eye, which is powered by a relativly large brain making it quite effective.

The grelken's true power is that they hunt is swarms making them able to hunt down a class called "super herbivores" which is a gargantuan herbivores of course, Because of the lower gravity herbivores have grown enormous, out of "reach" for almost every predator except the grelken and few others, most of them being "grelken relatives"
