Itorilleta look like a cross between a dinosaur, a spider and a scorpion of old Earth and crowned with a waving mass of sensitive tentacles. The twenty-metre tall beast lives in the jungle of Biggs Colony, Altair and waits patiently for prey. It has eight legs the size of small trees with a giant misshapen belly that's ten meters off the ground. It is supported on limbs which look spindly in comparison to the bulk above. The head peers myopically down at the jungle floor while the ring of sensory tentacles about its neck and head probes for situational awareness.
A thin tentacle, barely a decimetre in diameter can shoot out from under the eye ring, spearing towards prey. It can lift prey from the floor of the jungle high into the air and sweep to the creature's twin mouthed jaws. It carries two additional limbs which jut from the body just behind the neck.
It can let out a deafening roar which temporarily overwhelms that of the forest as a line of brilliant green pin-points flow along the length of the creature. It can rear up and with surprising agility span away to run into the jungle.
