Whitley, 1939
Very special thanks for the first photo of Neotrygon ningalooensis to Dr. Kirk R. Gastrich, he has take this photo in the Eastern Gulf of Shark Bay, Western Australia; 11th of September, 2009.
The Northern wobbegong occurs in shallow water and is often found in turbid areas.
Flattened benthic sharks with dermal lobes on sides of head, symphysial groove on chin, variegated but rather sombre colour pattern of rounded, ocellate dark dorsal saddles with entire edging and light margins, interspaced with broad dusky areas without spots or reticular lines; also, mouth in front of eyes, long, basally branched nasal barbels, nasoral
grooves and circumnarial grooves, two rows of enlarged fang-like teeth in upper jaw and three in lower jaw.
Diagnostic Features: Nasal barbels without branches. Two dermal lobes below and in front of eye on each side of head; dermal lobes behind spiracles unbranched and broad. No dermal tubercles or ridges on back. Interspace between dorsal fins longer than inner margin of first dorsal fin, about half first dorsal-fin base. Origin of first dorsal fin over about last fourth of
pelvic-fin base. First dorsal-fin height about equal to base length. Colour: colour pattern variegated but dull and sombre compared to most other wobbegongs, dorsal surface of body with small, rounded, ocellate, light-edged saddle marks with entire margins, separated from each other by broad, dusky spaces without spots or broad reticulated lines.
Distribution: Western South Pacific: Confined to Australian waters (Queensland, Northern Territory and Western Australia).
Habitat: A little-known but possibly common tropical inshore bottom shark of the Australian northern continental shelf. Occurs on shallow-water reefs in water less than 3 m deep, often in turbid areas.
Biology: A nocturnal shark, inactive during the day,sometimes seen with its head under a ledge. Probably ovoviviparous.
Presumably feeds on bottom invertebrates and fishes, but diet unrecorded.
Size: Maximum to at least 63 cm and possibly 100 cm; a
45 cm male was mature.
Interest to Fisheries and Human Impact: Interest to fisheries none at present. Conservation status unknown.
Local Names: Northern wobbegong, North Australian wobbegong
Literature: Whitley (1939, 1940); Marshall (1965); Compagno (1984); Michael (1993); Last and Stevens (1994).

Shark bites can be quite lethal to humans, especially the 10 most dangerous shark species are considered and can launch unprovoked attacks from humans: - Great white shark - Bull shark - Tiger shark - Sand tiger shark - Blacktip shark - Bronze shark - Spinner shark - Blue shark - Hammerhead shark - Whitetip shark The bite by a shark is one of the most basic fears of humans, but the number of deaths caused by shark attacks is very low: in 2015 there were 98 attacks by sharks and in 6 cases the attack resulted in a fatal end for humans. In 2016 there were 107 attacks by sharks and in 8 cases the attack resulted in a fatal end for humans.

In 2022, there were a total of 108 shark attacks in the USA.
Conversely, however, 100 million sharks were killed by humans. http://www.zeit.de/2016/37/haie-toetung-tierschutz-surfer The risk of being bitten by a shark varies greatly from region to region, with most attacks occurring in Florida, Australia and South Africa. Please be careful not to go into the water with bleeding skin wounds, heed bathing warnings from the authorities and be very careful when using surfboards, as sharks can easily confuse the boards with seals and harbour seals. After shark bites, always call a doctor or / and the rescue service as soon as possible, as heavy bleeding can be life-threatening.
