Ænima is Tool's first studio album to feature former Peach bassist Justin Chancellor.
The title Ænima is a blend of the words 'anima' and 'enema'. 'Anima' is Latin for 'soul' and is associated with the concept of "life force," a term often explored by psychologist Carl Jung. 'Enema' refers to the medical procedure involving the injection of fluids into the rectum.
To promote the album, singles were released in the following order: "Stinkfist," "H.," "Ænema," and "Forty-Six & 2," with music videos produced for "Stinkfist" and "Ænema." Several tracks on the album serve as segues or interludes, connecting longer songs and contributing to the album’s overall duration, which approaches the CD's maximum length of around 80 minutes. These segues include "Useful Idiot," "Message to Harry Manback," "Intermission," "Die Eier von Satan," "Cesaro Summability," and "(-) Ions."
