Campichthys tryoni is a species of marine fish of the family Syngnathidae. Little is known of this species, but the specimens that have been collected were found on the Queensland coast off of northeastern Australia. It is a rare mainly tan coloured pipefish with brownish markings, it has a white blotch over the eyes, a pale patch above the operculum and it has small white dots along its back and tail. The males frequently show irregular dark barring along their ventral surface. This species is ovoviviparous, with males carrying eggs in a brood pouch until giving birth to live young. The largest known specimen is 7.2 centimetres (2.8 in) long, while males may brood at roughly 6–6 centimetres (2.4–2.4 in). The species was described by James Douglas Ogilby in 1890 from a specimen collected in Moreton Bay, Queensland in 1886 and the specific name honours his friend, Mr Henry Tryon, with whom he enjoyed a collecting trip in Moreton Bay. It is a listed Marine species in Australia under the Environment Protection and Biodiversity Conservation Act 1999.

The Butler's frogfish or blackspot anglerfish, Tathicarpus butleri, is a rare species of frogfish in the family Antennariidae. The only member of its genus, this species is the most derived member of its family and represents a separate lineage from all other frogfishes, leading to some consideration of it being placed in its own family. It is found off the southern coast of New Guinea, and along the coasts of Western Australia to 33° S latitude, the Northern Territory, and Queensland to 22° S latitude. A benthic species, it inhabits inshore tropical waters and coral reefs to a maximum depth of 145 m (476 ft), though most are found shallower than 45 m (148 ft). Its specific epithet is after its discoverer Dr. Graham Butler.
