Taxonomic Remarks
A more detailed taxonomic review of the Eastern versus Western Atlantic M. hypostoma populations is needed to elucidate whether there are population-level differences, or if those differences simply reflect the low sample size available.

Cephalic fins smaller, tail longer without spine (Ref. 7251). Upper surface black (Ref. 6902).
Body shape (shape guide): other.
Occurs in shallow coastal waters (Ref. 12951). Feeds mainly on planktonic crustaceans but may take small schooling fishes (Ref. 12951). Ovoviviparous (Ref. 50449). Found singly, in small groups, and in schools (Ref. 12951). Swimming at high speed and often leap high above the surface (Ref. 6902). Feeds mainly on planktonic crustaceans, but also on small schooling fishes (Ref. 114953). Meat used for food and a source of oil (Ref. 6902).
دورة الحياة وسلوك التزاوج
النضج | التكاثر | وضع البيض | بيض | الخصوبة | اليرقات
Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures (Ref. 50449). Copulation has been observed to be in a venter to venter position while the pair swims at the surface. Mating reported to last 10 minutes. Litter number 1 (Ref. 12951).
