The Whale-squids resemble large pale skinned squid. They have a series of blue eyes that line their head. Closely related to the Hideauze, the whale-squids possess physiology that is more adapted to aquatic life than the vacuum of space. Infant whale-squids seem to appear more humanoid.
When the Evolvers departed Earth to escape the Second Ice Age, several were left behind. Those that remained, under Earth's ice regressed into semi-intelligent creatures. After the ice melted and ocean levels rose, they coexisted with the human populace. In many maritime cultures of the Earth, whale-squids were regarded as sacred creatures.
