The gummy shark, also known as the Australian smooth hound, flake, sweet william or smooth dog-shark, is a shark in the family Triakidae. These small to medium-sized bottom-dwelling sharks are found mostly in, but are not limited to, the area around the southern seas of Australia and is commonly baited and fished for cuisine because of its taste and market prices. According to a 2021 paper by White, Arunrugstichai & Naylorn (2021), Mustelus walkeri is the same animal as M. antarcticus. One theory is that M. walkeri is a subpopulation of M. antarcticus.
The crested bellowsfish or crested bellowfish, Notopogon lilliei, is a species of fish from the family Macroramphosidae. It is a demersal species which occurs over the continental shelf at depths of 80 to 600 m. They grow to lengths of up to 27 cm (11 in).
Macroramphosus, snipefishes or bellowfishes, is a genus of fishes found in tropical and subtropical oceans at depths down to 600 metres (2,000 ft). According to FishBase, they are part of the family Centriscidae, but Nelson (2016) split that family, in which case the genus Macroramphosus is in the family Macroramphosidae. They have long second spines on their dorsal fins and tiny mouths at the tip of their greatly elongated snouts. The bodies of snipefish are more streamlined than in the related bellowfishes. They reach a maximum length of about 20 cm (7.9 in), and are silvery or reddish in colour. They are sometimes found in large schools. This is the only genus on the monogeneric family Macroranphosidae but some authorities include the genera Centriscops and Notopogon in this family too.
The bellowfishes or bellowsfishes are fishes in the genus Notopogon in the family Centriscidae. They are found in deeper parts of the temperate southern oceans, although the longspine bellowfish has been recorded as far north as New Caledonia and Madagascar. According to FishBase, they are part of the family Centriscidae, but some authorities split that family, in which case the genus Notopogon is in the family Macroramphosidae, which is followed here. They have long second spines on their dorsal fins and tiny mouths at the tip of their greatly elongated snouts. Their bodies are relatively high, unlike the related snipefishes. They reach a maximum length of about 34 cm (13 in), and are silvery or reddish in colour.
