[3][4][5] Most Tibia fusus live in tropical offshore waters where there is plenty of sand, at depths of 5 to 50 m.[3] The shells of Tibia fusus can reach a length of 15–31 centimetres (5.9–12.2 in) (including the long siphonal canal), with a typical length of 23 cm (9 in.).

[5] These shells are large, spindle-shaped with moderately convex turns and an extremely long, thin and slightly curved siphonal canal.

The aperture is ovate and white inside, with 6 fingerlike growths on the outer lip.

[3] It is a fairly common species where it occurs, but because of its attractive appearance, it is highly sought after by shell collectors.

[3] Embryos develop into free-swimming planktonic marine larvae (trochophore) and later into juvenile veligers.
