Description
Dorsal spines (total): 10; Dorsal soft rays (total): 9; Anal spines: 3; Anal soft rays: 7; Pectoral fin rays: 16; Lateral line scales: 44-47. Head scales reaching forward to or just in front of level of anterior nostrils. Scaled area between nostrils with a distinct naked medial wedge-shaped notch. Suborbital scaly posteriorly. Scales rows on cheek: 4-5; Enlarged canines on jaws; Lower limb of preopercle with 2-3 scale rows. Pelvic fins moderately long, reaching to or almost to level of anus. Upper lobe of caudal fin slightly longer than lower. Axillary scale present. Max. length: 35.0 cm TL, common length: 15.0 cm SL. Depth range: 2 - 35 m.
Color
Upper body pale blue, lower whitish.
Etymology
Pentapodus: from ancient Greek, pénte = five + from Greek, podus or podos = feet. According to Valenciennes (1835), who called the genus “Pentapus,” referring to three long, pointed scales, one above root of each ventral fin and a single one between them, appearing like five ventral fins.

Original description: Scolopsides caninus Cuvier, 1830 - Type locality: Havre-Dorey, New Guinea.
Distribution
Western Pacific: Indonesia east to Marshall Islands and New Ireland (Papua New Guinea), north to southern Japan, south to northern Australia and New Caledonia.
Biology
Usually found close to the bottom over coral reef areas. Feeds on small fishes and larger zooplankton, as well as on benthic organisms. Occurs solitary or in small groups.

Pentapodus berryae (Allen, Erdmann & Brooks, 2018) - Reported from East Cape area, Milne Bay Province, Papua New Guinea.
Pentapodus aureofasciatus (Russel, 2001) - Reported from New Caledonia - Link to the species (here).
Pentapodus emeryii (Richardson, 1843) - Reported from Eastern Indian Ocean, western Pacific: Brunei, Malaysia and Indonesia east to Philippines and New Ireland (Papua New Guinea), south to northern Western Australia. The difference is with the width of the stripes. The Pentapodus aureofasciatus has stripes of equal size on back and side. The Pentapodus emeryii has a wider mid-lateral stripes.
