The anchored hydroglobe split from its ancestors that arrived in Blitz Polar Coast. Finding the rocks already encrusted with polar hydroglobes, it had to attach to the ground. However, thick carpets of polagea were already present, so the anchored hydroglobe evolved a hollow root-like anchor so that it could float above the competition without being washed away with the current. The hydroglobe itself is only 2 cm tall, and the "anchor", though thin and flexible, adds several centimeters to its height. It has developed a form of biological antifreeze in order to allow it to grow this far north of the equator in these cold icy waters that are frequented by icebergs.
