title: Near-term embryos in a Pristis pristis (Elasmobranchii: Pristidae) from Brazil.
abstract: This paper describes the record of a gravid Pristis pristis from the north coast of Maranhão State (Brazil) in May of 2009 by an artisanal vessel. Size, mass and rostrum length of the adult female were estimated at 5000 mm, 750000 g and 1536 mm, respectively. Total length (LT ) of miscarried embryos ranged from 755 to 800 mm and total mass from 890 to 1120 g. Although this is a single record, it indicates that P. pristis births may be taking place during May or coming months and there may be population differences between Central and South America.
