Etymology: Siganus: Latin, siganus = a fish, rabbit fish; by the similarity of the nose (Ref. 45335); woodlandi: Named for David J. Woodland of the University of New England, New South Wales, in recognition for his systematic research on Siganidae..

Morphology | Morphometrics
soft rays: 9;
Vertebrae: 23. Diagnosis: Pectoral rays 17-18. Scale rows above the lateral line 20-23. Gill rakers 6-7 + 17-18. Body depth 2.35-2.4 in SL; head length 4.1-4.4 in SL; snout length 2.4-2.6 in HL; longest dorsal spine 2.05-2.1 in HL. Dorsal profile of head from above front of eye to tip of recumbent dorsal spine concave. Caudal fin deeply emarginate, caudal concavity 1.35 in HL. The head and body light blue in life, with many small pale yellowish spots and very irregular narrow yellow bands, resulting in a fine reticular pattern for most of head and body (Ref. 55950).
Presumably feeding on zooplankton, but may only be opportunistic. Digestive tract of type specimen filled with benthic algae (Ref. 55950).
