Aquarius is the debut studio album by English progressive metal band Haken.

[3] It is a concept album about a mermaid, discovered by a fisherman and sold to a circus, whose blood is the only thing capable of saving the human race from a flood resulting from global warming issues.

[2] The album artwork was created by Dennis Sibeijn,[3] who has also worked with 3, Job for a Cowboy, and See You Next Tuesday, among others.

Her blood was able to create a cure that turns humans into mermaids giving them the ability to survive the flood.
