Short Description
Diagnosis after WHITE, LAST, NAYLOR, JENSEN & CAIRA, 2010 [9068]: A large Aetobatus (reaching at least 300 cm DW) with the following combination of characters: dorsal surfaces with a dark greenish grey base coloration, variably white spotted (rarely ocellated); different NADH2 gene structure; relatively long tail (mean total length 281% DW, mean anterior cloaca to tail tip 230.2% DW); stinging spines relatively long (mean length of first spine 9.7% DW); teeth plates in a single row, those in lower jaw chevron-shaped; pectoral-fin radials about 102–116 (excluding proterygial radials anterior of eyes); total vertebral centra (including synarcual) 99–101.

Distribution
Tropical and subtropical Indo–West and Central Pacific, also likely to be present in the Western Indian Ocean. [9068]

Biology
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 [733].

Size / Weight / Age
Last & Stevens (2009) [3365] report that in Australia, this species (as A. narinari) attains up to 3000 mm DW (>8800 mm TL), with males and females maturing at 1000 and 2140 mm DW respectively, and born at 180–260 mm DW. [9068]

Habitat
benthopelagic; marine
