Steven's swellshark (Cephaloscyllium stevensi) is a species of swellshark which resides in the waters around Papua New Guinea. It was described by Clark and Randall in 2011. [1]
Papua New Guinea, officially the Independent State of Papua New Guinea, is a country in Oceania that comprises the eastern half of the island of New Guinea and its offshore islands in Melanesia. Its capital, located along its southeastern coast, is Port Moresby. The country is the world's third largest island country with an area of 462,840 km2 (178,700 sq mi).
Western New Guinea, also known as Papua, Indonesian New Guinea, or Indonesian Papua, is the western portion of the Melanesian island of New Guinea which is administered by Indonesia. Since the island is alternatively named as Papua, the region is also called West Papua. Lying to the west of Papua New Guinea and considered a part of the Australian continent, the territory is mostly in the Southern Hemisphere and includes the Schouten and Raja Ampat archipelagoes. The region is predominantly covered with ancient rainforest where numerous traditional tribes live such as the Dani of the Baliem Valley although a large proportion of the population live in or near coastal areas with the largest city being Jayapura.

Cephaloscyllium is a genus of catsharks, and part of the family Scyliorhinidae, commonly known as swellsharks because of their ability to inflate their bodies with water or air as a defense against predators. These sluggish, bottom-dwelling sharks are found widely in the tropical and temperate coastal waters of the Indian and Pacific Oceans. They have stocky, spindle-shaped bodies and short, broad, and flattened heads. The mouth is capacious, containing many small teeth and lacking furrows at the corners. The two dorsal fins are placed far back on the body, with the first much larger than the second. Different species have various color patterns of saddles, blotches, reticulations, and/or spots. The largest members of the genus can grow over 1 m (3.3 ft) in length. Swellsharks prey on a variety of fishes and invertebrates, and are oviparous, with females producing egg capsules in pairs. They are harmless and have been deemed of having no commercial value.
The Australian swellshark or draughtboard shark, is a species of catshark, and part of the family Scyliorhinidae, endemic to southern Australia. This bottom-dwelling species can be found on the continental shelf down to a depth of 220 m (720 ft). Usually measuring 1 m long, it is a stout-bodied, broad-headed shark with a short tail and a first dorsal fin much larger than the second. It can be identified by its variegated dorsal coloration of brown or grey patches and numerous spots.
The blotchy swellshark, or Japanese swellshark, is a common species of catshark, belonging to the family Scyliorhinidae. The Blotchy swellshark is found at depths of 90–200 m (300–660 ft) in the northwestern Pacific Ocean, from Japan to Taiwan. It is benthic in nature and favors rocky reefs. Reaching 1.4 m (4.6 ft) in length, this thick-bodied shark has a broad head, large mouth, and two unequally-sized dorsal fins positioned far back past the pelvic fins. It can be identified by its dorsal coloration, consisting of seven brown "saddles" and extensive darker mottling on a light tan background. This species has often been confounded with the draughtsboard shark and the Sarawak pygmy swellshark in scientific literature.
Rothschild's woolly rat is a species of rodent in the family Muridae. It is found on the island of New Guinea: both in the West Papua region of Indonesia and Papua New Guinea.
The narrowbar swellshark is a rare species of catshark, and part of the family Scyliorhinidae, known only from two specimens collected near Flinders Reef off northeastern Australia. This species reaches at least 44.5 cm (17.5 in) in length, and has a stocky body with a short, broad head. It can be readily identified by its zebra-like dorsal color pattern of transverse brown bars on a yellowish background. Like other swellsharks, it can inflate its body as a defensive measure.
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.
Orania is a genus of the palm tree family Arecaceae, and includes flowering plants native to Southeast Asia, Madagascar, and New Guinea.
The continent of Australia, sometimes known in technical contexts by the names Sahul, Australia-New Guinea, Australinea, Meganesia, or Papualand to distinguish it from the country of Australia, is located within the Southern and Eastern Hemispheres. The name "Sahul" takes its name from the Sahul Shelf, which is part of the continental shelf of the Australian continent. The continent includes mainland Australia, Tasmania, the island of New Guinea, the Aru Islands, the Ashmore and Cartier Islands, most of the Coral Sea Islands, and some other offshore continental islands. Situated in the geographical region of Oceania, Australia is the smallest of the seven traditional continents.
New Guinea is the world's second-largest island with an area of 785,753 km2 (303,381 sq mi). Located in Oceania in the southwestern Pacific Ocean, the island is separated from Australia by the 150-kilometre wide Torres Strait, though both landmasses lie on the same continental shelf. Numerous smaller islands are located to the west and east. The eastern half of the island is the major land mass of the independent state of Papua New Guinea. The western half, known as Western New Guinea, forms a part of Indonesia and is organized as the provinces of Papua, Central Papua, Highland Papua, South Papua, and West Papua. The largest cities on the island are Jayapura and Port Moresby.
Macroglossum dohertyi is a moth of the family Sphingidae. It is known from Queensland and Papua New Guinea.
Macroglossum stevensi is a moth of the family Sphingidae. It is known from Papua New Guinea.
The Cook's swellshark is a little-known species of catshark, belonging to the family Scyliorhinidae. This shark is found in the Arafura Sea at a depth of 223–300 m (732–984 ft). It is a stocky-bodied shark with a short, broad head and a large mouth, and can be identified by the eight dark, pale-edged saddles along its grayish brown body and tail. The maximum known length of this species is 30 cm (12 in). Like other swellsharks, it can inflate itself with water or air when threatened.
The Australian reticulate swellshark is a little-known species of catshark in the family Scyliorhinidae. It is found off the coast of northwestern Australia at depths of 290–420 m (950–1,380 ft). This shark has a stocky body and a short, wide head with a capacious mouth. It is characterized by a striking dorsal color pattern of dark brown lines that trace a series of hollow saddles and narrow rings, on a light background. Like other swellsharks, this species can inflate itself when threatened. Its reproduction is oviparous.
The painted swellshark is a little-known species of catshark, belonging to the family Scyliorhinidae, found in eastern Indonesia. This species reaches a maximum known length of 72 cm (28 in), and has a thick body with a short, broad and flattened head. It is dark gray with a variegated pattern of irregular darker and lighter blotches above, and lighter below with gray blotches and speckling on the snout. Like other swellsharks, it can inflate itself as a defensive measure.
Ambulyx dohertyi is a species of moth of the family Sphingidae first described by Walter Rothschild in 1894.
