Eye diameter less than 1.5 times in snout length, less than 1.1 times in interorbital width, and less than 5 times in head length; head length the same as body depth; lower and upper jaw close equally or lower jaw extends anteriorly from upper jaw; usually a well developed nuchal hump.

Occurs over muddy, sandy and rocky substrates (with slight preference for rocks), usually in water deeper than 3 m. Feeds on insects (both larvae and adults); small specimens also eat zooplankton, while large ones sometimes exclusively feed on fish (Ref. 35835).
生活在泥濘的沙與岩石底部 (有輕微的對岩石的偏愛) 之上, 通常在深度超過 3 公尺的水域。 吃昆蟲 (仔魚和成魚); 小的標本也吃浮游動物而大的一些有時專門地吃魚。 (參考文獻 35835)
