We present the first observations of molecular line emission in NGC~ { } 3718 with the IRAM 30m and the Plateau de Bure Interferometer .
This galaxy is an impressive example for a strongly warped gas disk harboring an active galactic nucleus ( AGN ) .
An impressive dust lane is crossing the nucleus and a warp is developing into a polar ring .
The molecular gas content is found to be typical of an elliptical galaxy with a relatively low molecular gas mass content ( \sim 4 \times 10 ^ { 8 } \mbox { $ \mathcal { M } _ { \odot } $ } ) .
The molecular gas distribution is found to warp from the inner disk together with the HI distribution .
The CO data were also used to improve the kinematic modeling in the inner part of the galaxy , based on the so-called tilted ring -model .
The nature of NGC~ { } 3718 is compared with its northern sky “ twin ” Centaurus A and the possible recent swallowing of a small-size gas-rich spiral is discussed .
