Western Atlantic: Maryland in the USA, Bermuda and Bahamas to Rio de Janeiro, Brazil (Ref. 13628), including the West Indies (Ref. 3802); absent in the northern Gulf of Mexico.
Length at first maturity / आकार / वज़न / Age
Maturity: Lm ?, range 31 - ? cm
Max length : 120 cm TL पुल्लिंग / अलिंग; (Ref. 7251); common length : 35.0 cm TL पुल्लिंग / अलिंग; (Ref. 3802)
पृष्ठीय रीढ़ (सम्पूर्ण) : 9; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 10; गुदा कांटा: 2; ऐनल सौफट रेज़: 9. Adults uniformly blue, with yellow area on top of head that disappears in larger fish.
