Neotrygon australiae
A whiptail stingray caught for local delicacy in Indonesia and Papua New Guinea.
The Australian bluespotted maskray, *Neotrygon australiae*, is a whiptail stingray whose range includes Australia, Indonesia, and Papua New Guinea. Local trawlers frequently catch this ray, and in Indonesia and Papua New Guinea it may be kept as a local food item.
Several features set it apart from its close relative, *Neotrygon kuhlii*. It has a much wider disc, narrowly pointed pectoral tips, and a fleshy snout that is either rounded or only weakly angular. Its tail is very long, with black-and-white bars near the rear and a ventral fold that is entirely dark. The body color ranges from reddish brown to greenish, covered with large blue spots and small, peppery dark spots. The largest recorded female measured 45.2 cm across the disc.
This species is found in the Northern Territory, Western Australia, and Queensland in Australia; the Lesser Sunda Islands and southern Papua in Indonesia; Timor-Leste; and Papua New Guinea. It lives in inshore habitats from the surface down to about 90 meters. Although it is not known to be kept in Australia, local fisheries in Indonesia and Papua New Guinea catch it—either on purpose or as bycatch—and it is likely used for human consumption there.

Lore & Background
Neotrygon australiae can be distinguished from its closest congener, Neotrygon kuhlii, by several characteristics: a much broader disc, narrowly angular pectoral apices, a rounded or weakly angular fleshy snout, an entirely dark ventral tail fold, a very long tail with black-white bars on the rear, reddish brown to greenish body color, and coverage of large blue spots and small peppery dark spots. The maximum size recorded for female specimens is 45.2 cm disc width.
The species inhabits inshore habitats ranging from the surface to a depth of around 90 m. Its distribution encompasses Northern Territory, Western Australia, and Queensland in Australia; the Lesser Sunda Islands and southern Papua in Indonesia; Timor-Leste; and Papua New Guinea.
It is caught, either as target or bycatch, by local fisheries and will likely be used for human consumption in the regions of Indonesia and Papua New Guinea, although it is not known to be retained in Australia.
Reader's Guide
The Australian bluespotted maskray holds significance as a species that is both targeted and taken as bycatch in local fisheries across its range. In Indonesia and Papua New Guinea, it is retained for human consumption as a local delicacy, indicating its role in regional food traditions. In contrast, it is not known to be retained in Australia, suggesting differing fishing practices or cultural attitudes toward the species. The ray's distinctive appearance—with large blue spots and small peppery dark spots on a reddish brown to greenish body, along with a long tail bearing black-white bars—makes it visually notable among whiptail stingrays. Its maximum recorded disc width of 45.2 cm for females provides a size benchmark. The species' inshore habitat and depth range from the surface to around 90 m place it within reach of small-scale fisheries. The article does not assess population status or conservation measures, but the fact that it is caught and consumed in parts of its range highlights its ongoing interaction with human activities.
