Jujubee Polar Flasher
Those glacial flash cells which ended up on the edges of the great tundra sheets of the North Polar Glacier sometimes ended up within the oceanic waters just beyond it, and of these, they sometimes survived the encounter with the icy cold waters of the arctic regions of the Jujubee Ocean. Those that did eventually evolved into a closely related species, known as the jujubee polar flasher. As they no longer live on the glacial sheets, they have not replaced their ancestors.
They still live in large plumes, although now that they live in the open ocean they behave differently. Instead of using their heat organelle to keep their home pools above freezing temperature, they instead cluster together in large enough amounts to help keep their own body temperatures up high enough to survive the frigid temperatures. This works in the same way as larger beings huddling together for warmth by combining their body heat, but since they have heat organelles it works even better. In fact, it can work so well that if an organism that's built to survive only in colder temperatures could even perish, as if clouds combine into huge clouds, they can bring the temperatures well above freezing, although the temperature is still well below that of temperate regions.
They will still signal to those in lower sections of their clouds, doing so after an oceanic storm. Dormancy is still the norm for their species, as well.
