The rhino filefish (Pseudalutarius nasicornis) is a slender filefish with a long horn-like spine above its eyes. Dark stripes run along its pale body.

It grows to about 15-19 cm and swims head-down among sea pens, soft corals and seagrass. It feeds on small invertebrates.

In the Philippines it is found on sand and rubble slopes, often close to sea whips or sea pens.
