Whitley’s Gurnard Perch, Maxillicosta whitleyi Eschmeyer & Poss, 1976
Whitley’s Gurnard Perch has previously been confused with Southern Gurnard Perch, Maxillicosta meridianus. The species can be separated by different caudal fin markings (in preserved specimens) and nasal spine morphology. For additional differences, see Motomura et al (2006).
Whitley’s Gurnard Perch has large eyes, a large oblique mouth and groove behind the eyes. The species is endemic to the east coast of Australia.
Whitley’s Gurnard Perch has large eyes, a large oblique mouth and groove behind the eyes. It can be recognised by a combination of characters that include a lack of reticulated colour pattern on the body and 19 to 22 pectoral fin rays. There are 40 to 47 scales in the longitudinal series and 25 to 28 pored lateral line scales. The nasal spines have 3 to 12 spinous points on the anteriormargin. The caudal fins of preserved specimens usually have three or four narrow irregular vertical bands.
The species is named in honour of Gilbert Whitley, Fish Curator at the Australian Museum for 42 years (1922-1964).
The species is usually found at a depth of 41 m - 82 m.
The species is endemic to the east coast of Australia, occurring from southern Queensland to north-eastern Victoria.
