Belelup IV

Belelup IV
A few islands are dotted around an ocean mostly free of ice, except at the poles. Large water-filled caves are present just beneath the surface. A thin dusting of light green lichen covers the land.
Every nineteen years, billions of segmented creatures hatch all at once and begin to swarm, eating everything in their path. They exude a sticky slime when threatened.
Due to a celestial conjunction, the planet is plunged into darkness every nineteen years.
