Under Evynnis, this species is chracterized by the following set of characters: D XII,10, with the first and second spines considerably shorter than third and fourth spines which are extended, and the third dorsal fin spine less than 2 time in fifth dorsal fin spine; A III,9; pectoral fin rays usually 15; scales on preopercular flange absent; body depth relatively lower, standard length/body depth over 2.1; when fresh, with scattered cobalt blue spotted markings on side; teeth on vomer usually present (Ref. 75039).

Edwardsiellosis. Bacterial diseases

Dorsal spines (total): 12; Dorsal soft rays (total): 10; Analspines: 3; Analsoft rays: 9

Inhabits muddy and muddy-sandy bottoms. Feeds on a wide range of benthic invertebrates and on fish. Two spawning seasons, early summer and autumn. Utilized for human consumption especially in the East China Sea where it is caught mostly by trawlers. An important food fish.

分布於印度-西太平洋區，西起印尼，北至日本，南至澳洲。台灣分布於北部、西部、東北部、南部及澎湖海域。

全年皆有產，但以初夏及秋季為盛產，是美味的高經濟價值魚種，可利用延繩釣、手釣等漁法捕獲，碳烤、油炸、清蒸皆可。

與紅鋤齒鯛(/Evynnis cardinalis/)極為相似，其差別如下：1. 背鰭第IV棘長度不及第V棘的2倍(紅鋤齒鯛超過3倍)；2.魚體新鮮時，體側散在些許的鈷藍色小點(紅鋤齒鯛則有數列縱向且顯著的鈷藍色點狀線紋)3.通常具有鋤齒鯛(紅鋤齒鯛退化而不顯著，甚至沒有)。目前本屬(/Evynnis/)的分類尚未完成，仍須再進一步研究。以前所記載之赤鯮/Dentex tumifrons/ (Temminck & Schlegel, 1843)為黄背牙鯛/Dentex hypselosomus/或是阿部牙鯛/Dentex abei/的誤鑑。

主要棲息於大陸棚砂泥底水域，棲息深度在50-250公尺之閻。每年6-7月及10-11月是其產卵期。肉食性，以底棲生物為主食。
