IC 2531 is an edge-on spiral galaxy located in the constellation of Antlia.

[5] It is seen edge-on and contains a dust lane found separating its main body into two equal components.

[4] It has a presence of filamentary features reaching its galactic halo[6] and high circular velocity of vmax = 260.5 km−1.

[5][4] Through analyzations of its atomic hydrogen (HI) content as part of the Herschel observations,[8] a total mass of 1.37 x 1010 MΘ was calculated.

It is found having outer regions slightly wrapped along its line of sight and the plane of the sky with both inclination and position angles straying 4 degrees.
