Percis matsuii is a fish in the family Agonidae. It was described by Matsubara in 1936.[1] It is a marine, deep water-dwelling fish which is known from southern Japan, in the northwestern Pacific Ocean. It dwells at a depth range of 200mto500mm (700feetto1,600feetm), and inhabits sand and mud sediments. Males can reach a maximum standard length of 15cm (06inches).
Due to its moderately wide distribution in its region, and due to a lack of interest from fisheries, the IUCN redlist currently lists P. matsuii as Least Concern.
