Zelorgbian creatures are relatively simple jellyfish-related invertibrates that live on the edges of the ocean. Zelorgbians come on shore to bask in the sunlight and to lay their eggs. However, they can't move on land and risk dehydration if they're beached, so they choose to stay as close to the water's edge as possible. They are very sociable and will often move in huge herds, which sometimes get swept long distances by strong ocean currents.
