Widespread: common in the tropical western Atlantic; Eastern Atlantic: from Portugal to Angola), the Mediterranean. Western Indian Ocean: off southern Somalia to Zanzibar, off Mozambique to Durban, along the Mascarene Ridge and off Maldives (Ref. 98298); including Gulf of Aden and Zanzibar (Ref. 26165).

Length at first maturity / আকৃতি / ওজন / Age

Maturity: Lm 2.7, range 3 - 4 cm
Max length : 25.0 cm TL পুরুষ/ লিঙ্গ অনিধর্ারিত ; (Ref. 3397); সর্বোচ্চ উলি্ল্লখিত বয়স : 9 বৎসর (Ref. 58045)

জীববিজ্ঞান     শব্দকোষ (উদাহরণ স্বরূপ epibenthic)

Most common at depths less than 500 m (Ref. 1371). Feeds predominantly on pelagic copepods, to a lesser extent on euphausiids and gammarian amphipods, and to a minor extent on shrimps, ostracods, cumaceans, other small crustaceans, and small fish (Ref. 1371). Due to its small size, it is not of significant interest to fisheries (Ref. 1371).
