[4] When Pieter Bleeker described the genus Paracentropogon he designated A. longispinis as its type species.

[3] The dorsal fin has its origin in the intraorbital area the membranes between the spines are deeply notched.

Its range extends from southern India, Thailand, and Malaysia through Indonesia to western, northern, and eastern Australia.

[3] Paracentropogon longispinis is found at depths from 2 to 60 ft on sandy, silty, muddy, or rubble bottoms, and also in fields of Zosteraceae.

It is a nocturnal benthic species, an ambush predator, feeding by hunting from a hide by mimicking a crumpled, dead leaf or a drifting piece of seaweed.
