The Agulhas Bank is a broad, shallow part of the southern African continental shelf which extends up to 250 km (160 mi) south of Cape Agulhas before falling steeply to the abyssal plain.
The tiger catshark is a species of shark belonging to the family Pentanchidae, the deepwater catsharks. It is found over sandy areas and near reef peripheries off South Africa and perhaps Mozambique, from close to shore to usually no deeper than 100 m (330 ft). Reaching a length of 50 cm (20 in), this small, slim shark has a broad, flattened head with an upturned snout tip. It can additionally be identified by its dorsal colour pattern of ten dark brown saddles on a yellowish brown background.
The Australian sawtail catshark is a common species of deepwater catshark, belonging to the family Pentanchidae, endemic to southern Australian waters. It is found on or near the bottom of the outer continental shelf and upper continental slope, at depths of 85 to 823 m. This slim-bodied species is characterized by crests of enlarged dermal denticles along both the dorsal and ventral edges of its caudal fin and caudal peduncle, along with a color pattern of broad, dark saddles outlined in white. It can grow to 61 cm (24 in) in length. The Australian sawtail catshark feeds mainly on fishes, crustaceans, and cephalopods. Females are oviparous and lay eggs enclosed by capsules. This species is often caught incidentally by commercial bottom trawl fisheries, but is not significantly threatened by fishing activity. Thus, it has been assessed as of Least Concern by the International Union for Conservation of Nature (IUCN).
The dwarf sawtail catshark is a species of shark belonging to the family Pentanchidae, the deepwater catsharks. This shark is found exclusively in the deep waters off Luzon in the Philippines. Unlike other members of its genus, this slender, diminutive shark has a short, rounded snout and very short furrows at the corners of its jaws. It has indistinct darker saddles beneath each dorsal fin and two dark bands on the caudal fin, as well as a prominent crest of enlarged dermal denticles along the upper caudal fin margin.
The speckled swellshark is a little-known species of catshark, and part of the family Scyliorhinidae, endemic to the waters off northwestern Australia. It occurs on the outer continental shelf and upper continental slope, at a depth of 150–455 m (492–1,493 ft). This species grows to 69 cm (27 in) long and has a stocky body and a short, broad, flattened head. As its common name suggests, its color pattern consists of many dark spots and white-spotted dark saddles and blotches on a light gray background. The juveniles are yellow with dark spots and lines, and a distinctive eyespot-like mark behind each eye. Like other swellsharks, this species can inflate itself as a defensive measure.
The greenback stingaree is a little-known species of stingray in the family Urolophidae, endemic to the outer continental shelf and upper continental slope off southeastern Australia. Growing to a length of 51 cm (20 in), this species has a diamond-shaped pectoral fin disc wider than long and uniformly light green in color above. Between its nostrils is a skirt-shaped curtain of skin. Its tail bears skin folds on either side and a deep, lanceolate caudal fin, but lacks a dorsal fin.
The Integrated Marine and Coastal Regionalisation of Australia (IMCRA), formerly the Interim Marine and Coastal Regionalisation for Australia, is a biogeographic regionalisation of the oceanic waters of Australia's exclusive economic zone (EEZ). As of 2008, the most recent version is IMCRA Version 4.0.
The Central Western Shelf Province, also known as the Shark Bay marine ecoregion, is a biogeographic region of Australia's continental shelf and coastal waters. It includes the subtropical coastal waters of Western Australia.
The Southwest Shelf Transition, also known as the Houtman marine ecoregion, is a biogeographic region of Australia's continental shelf and coastal waters. It includes the subtropical coastal waters of Southwest Australia.
Orectolobus reticulatus, the network wobbegong, is a recently described species of carpet shark found in relatively shallow waters off Kimberley and Darwin in north-western Australia. With a known maximum length of only 52.3 centimetres (20.6 in), it may be the smallest species of wobbegong. Until its description in 2008, it had been confused with the northern wobbegong. The network wobbegong has a short snout, broad head, elongated body, and two dorsal fins, with the first being slightly larger than the second. Its body is grayish brown with darker brown markings and a pale yellow underbelly. The network wobbegong lives in shallow waters along reefy bottoms.
Leuconia is a genus of calcareous sponges in the family Baeriidae. It was described by English anatomist and zoologist Robert Edmond Grant in 1833.
Pteranodontoidea is an extinct clade of ornithocheiroid pterosaurs from the Early to Late Cretaceous of Asia, Africa, Europe, North America and South America. It was named by Alexander Wilhelm Armin Kellner in 1996. In 2003, Kellner defined the clade as a node-based taxon consisting of the last common ancestor of Anhanguera, Pteranodon and all its descendants. The clade Ornithocheiroidea is sometimes considered to be the senior synonym of Pteranodontoidea, however it depends on its definition. Brian Andres in his analyses, converts Ornithocheiroidea using the definition of Kellner (2003) to avoid this synonymy.
Billardiera fusiformis, commonly known as Australian bluebell, is a species of flowering plant in the family Pittosporaceae and is endemic to the south-west of Western Australia. It is a sturdy, shrubby climber that has linear to narrowly elliptic leaves and blue, white or pink, nodding flowers arranged singly or in groups of up to four.
Baeriidae is a family of calcareous sponges in the class Calcarea. It was named by Borojevic, Boury-Esnault, and Vacelet in 2000. The type genus is BaeriaMiklucho-Maclay, 1870, by original designation, though Baeria is now considered a junior synonym of LeuconiaGrant, 1833.
Vosmaeropsis macera is a species of calcareous sponge in the family Heteropiidae, and was first described in 1886 by Henry John Carter as Heteropia macera, and was later described as Vosmaeropsisis dendyi by Row and Hôzawa in 1931. It is the type species of the genus, Vosmaeropsis. The species epithet, macera, comes from the Latin, macer.
Vosmaeropsis mackinnoni is a species of calcareous sponge in the family Heteropiidae, and was first described in 1924 by Arthur Dendy and Leslie M. Frederick. It is known only from its type locality in the Abrolhos Islands, in Western Australia.
Heteropia is a genus of sponges in the family Heteropiidae, and was first described in 1886 by Henry John Carter. The type species by monotypy is Heteropia ramosa, which he first called Aphroceras ramosa in the very same publication.
Phycopsis is a genus of sponges belonging to the family Axinellidae. The species of this genus are found in Malesia and Australia.
Hibbertia glomerosa is a species of flowering plant in the family Dilleniaceae and is endemic to the south-west of Western Australia. It is a shrub with linear to narrow oblong leaves and bright yellow flowers borne on the ends of short side shoots, with twenty-five to thirty-eight stamens arranged in groups of five around the five glabrous carpels.
Amaryllis migo is a species of crustacean in the family Amaryllididae, and was first described in 2002 by James K. Lowry and Helen E. Stoddart.
