Morphology | Morphometrics
This large species is distinguished by the following characters: dorsal surfaces with a dark greenish grey base coloration, variably white spotted, rarely ocellated; different NADH2 gene structure; relatively long tail with mean total length 281% DW, mean anterior cloaca to tail tip 230.2% DW; stinging spines relatively long with mean length of first spine 9.7%DW; teeth plates are in a single row, those in the lower jaw chevron-shaped; pectoral fin radials about 102-116, excluding proterygial radials anterior of eyes; 99-101 total vertebral centra, including synarcual (Ref. 84291).
Found in coastal waters (Ref. 45255), including estuarine habitats (Ref. 89467). Feeds on gastropod, bivalve molluscs, crustraceans, worms, octopuses and fishes (Ref. 89467). Ovoviviparous (Ref. 50449).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
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).
