Panna is a genus of marine ray-finned fish belonging to the family Sciaenidae, the drums and croakers.

[1] O. microdon was described in 1849 by Pieter Bleeker, with its type locality given as Java.

[2] The genus Pachyurus is included in the subfamily Cynoscioninae by some workers,[3] but the 5th edition of Fishes of the World does not recognise subfamilies within the Sciaenidae, which it places in the order Acanthuriformes.

[4] Panna is a name that Lal Mohan did not explain but is thought to be a local name of the type species, P. macrodon in India.

[5] There are currently 3 recognized species in this genus:[6] Panna croakers have a swim bladder characterised by having a pair of tubular appendages starting at the head end which divides almost at its root into a simple rear part and either a simple or branched part at the head end, entering the head through the septum transversum.
