Upeneus mascareinsis, the Mascarene goatfish, is a species of marine ray-finned fish belonging to the family Mullidae, the goatfishes, which is found in the Indian Ocean.

Description[]

Upeneus mascareinsis has dorsal fins which have a total of 8 spines and 9 soft rays. The pectoral fins have 15-16 soft rays. The gill raker counts are 7-8 + 19-22. There are 35-38 scales in the lateral line. The body has a depth of 22-26% of the standard length at the base of the origin of the dorsal fin and of 18-22% of the standard length it the anus. The caudal peduncle has a depth of 8.3-9.3% of the standard length. Its barbels are 18-24% of the standard length. There are 7-10 total bars on caudal fin, 3-6 bars on the upper lobe which are pale brown near the base and dark brown to black towards the margin while the lower lobe has 3-4 brown bars which darken towards the margin and the last 2 bars being completely dark brown or black and widening towards the margin. There is a small bar on the tip of the lower lobe. The width of biggest lower caudal-fin lobe bar and/or the space between outermost bars is less than the diameter of the orbit. They doi not have any flank stripes and the tip of first dorsal-fin is dark, The barbels are white as is the belly while the flanks are rose-red darkening towards the back where there is some gold iridescence along the upper flanks and a dark saddle to the rear of the second dorsal fin. The body is uniformly brown, with a little dorsal darkening, with the bars and black first dorsal-fin tip still visible in preserved fish.[1] This species attains a standard length of 18 centimetres (7.1 in).[2]
