[4] The Antlia Wall,[4] also known as the Antlia Strand,[6][7][5] Hydra Wall,[8] Hydra-Antlia wall, Hydra-Antlia extension,[9] and the Hydra-Antlia filament,[10] is a filament that emeges from the Centaurus Cluster, passes under the Zone of Avoidance (ZOA) as the "Puppis filament",[6] to link up the Lepus Cloud.

[4] This filament then passes though a region containing the NGC 1600 Group before crossing the boundary where the gravitional flows of galaxies between the Laniakea and Perseus–Pisces superclusters diverge[6] to link up with the Perseus–Pisces supercluster at a distance of around 420 Mly (130 Mpc) from the Centaurus Cluster.

[11] Later in 2017, Pomarède et.al identified based on the flow of galaxies that the Antlia Wall along with the Lepus Cloud are part of a substantial filament known as the Centaurus–Puppis–PP Filament[6] that extends around 420 Mly (130 Mpc) from the Centaurus Cluster all the way to the Perseus–Pisces supercluster.

Before 2017, it was not known that the Antlia Wall and the Lepus Cloud were part of the same structure, the Centaurus–Puppis–PP Filament.

Within the proximity of this supercluster lies the Great Attractor, dominated by the Norma Cluster (Abell 3627).
