Balanoglossus australiensis is a species of 20 centimetres (7.9 in) long acorn worm in Ptychoderidae family which can be found in Gulf of Carpentaria, New Zealand, Western Australian cities such as Hawkesbury and Manning as well as Solomon Archipelago and its sea. Their habitat consists of 8–10 inches (200–250 mm) deep sandy burrows where they feed on Ubius species.

The family Argulidae contains the carp lice or fish lice – a group of parasitic crustaceans of uncertain position within the Maxillopoda. Although they are thought to be primitive forms, they have no fossil record. The Argulidae are the only family in the order Arguloida, although a second family, the Dipteropeltidae, has been proposed.
Canthocamptus is a genus of copepods that live in water from the Arctic Ocean to the Atlantic Ocean. There are over 200 different species of Canthocamptus. A number of Australian endemic species are listed as vulnerable species on the IUCN Red List, and one Brazilian species is conservation dependent.
Canthocamptidae is a family of copepods. Most of the 700 species are confined to fresh water, although there are also marine species. It contains the following genera:
Saccoglossus is a genus of acorn worm. It is the largest genus in this class, with 18 species.
Astralium, common name star snails, is a genus of sea snails, marine gastropod mollusks in the family Turbinidae, the turban snails and star snails.
Munidopsis is a genus of squat lobster. It is the second largest of all the genera of squat lobsters, after Munida, with over 200 species. Its members are mainly found on continental slopes and on abyssal plains. A few fossil species are also known, including specimens from the Campanian (Cretaceous).
Harrimaniidae is a basal family of acorn worms. A taxonomic revision was undertaken in 2010 and a number of new genera and species found in the Eastern Pacific were described. There is some indication that Stereobalanus may be a separate basal acorn worm lineage, sister to all remaining acorn worms.
Rissoina is a large genus of minute sea snails, marine gastropod mollusks or micromollusks in the family Rissoinidae.
Amphianthus is a genus of sea anemones. It is the only genus in the monotypic family Amphianthidae.
Robertgurneya is a genus of copepods, containing the following species:
Balanophyllia is a genus of solitary corals in the order of stony corals.
John Dow Fisher Gilchrist (1866–1926) was a Scottish ichthyologist, who established ichthyology as a scientific discipline in South Africa. He was instrumental in the development of marine biology in South Africa and of a scientifically based local fishing industry.
Leptopsammia is a genus of stony cup corals in the family Dendrophylliidae. Members of this genus are found at depths down to about 900 metres (3,000 ft). They are azooxanthellate, meaning that they do not contain symbiotic photosynthetic algae as do many species of coral.
Dendrophyllia is a genus of stony cup corals in the family Dendrophylliidae. Members of this genus are found at depths down to about 900 metres (3,000 ft). They are azooxanthellate corals, meaning that they do not contain symbiotic photosynthetic dinoflagellates as do many species of coral.
Arthur Willey FRS was a British-Canadian zoologist.
Tillinae is a subfamily of beetles in the family Cleridae, the checkered beetles.
William Wardlaw Thompson was a South African ichthyologist and zoologist. It is known that he was educated at the South African College in Cape Town between 1858 and 1863 and that he obtained a post on the civil service of the Cape Colony in 1877 in the Railway Department as a temporary clerk.
