Daphnia is a genus of small planktonic crustaceans, 0.2–6.0 mm (0.01–0.24 in) in length. Daphnia are members of the order Anomopoda, and are one of the several small aquatic crustaceans commonly called water fleas because their saltatory swimming style resembles the movements of fleas. Daphnia spp. live in various aquatic environments ranging from acidic swamps to freshwater lakes and ponds.
Lumholtz's tree-kangaroo is a rare, long-tailed bear-like mammal found in rainforests in northeastern Australia. Like most tree-kangaroos, it lives alone in trees and feeds on plant matter. It belongs to the macropod family (Macropodidae) with kangaroos, and carries its young in a pouch like other marsupials. It is threatened by climate change and diseases, and is found in the hilly, fertile Atherton Tableland in Queensland.

The third species is Muscocyclops operculatus.
Neodiaptomus intermedius is a species of freshwater copepod, in the family Diaptomidae. It lives in South India's inland freshwater areas of the Nilgiri Hills, Tirmala Hills, Kaza, and at Shornur. It inhabits any bodies of water in plains or elevated hills.
Neodiaptomus is a genus of freshwater copepods in the family Diaptomidae. It contains the following species, four of which are listed as vulnerable species on the IUCN Red List :
Notodiaptomus is a genus of copepods in the family Diaptomidae. It is the most widely distributed, most abundant and most species-rich genus of freshwater calanoid copepods in the Neotropics. The genus was erected in 1936 by Friedrich Kiefer for eleven species formerly placed in a wider Diaptomus. Notodiaptomus deitersi was chosen to be the type species by Raúl Adolfo Ringuelet in 1958.
Skistodiaptomus is a genus of freshwater copepods in the family Diaptomidae, found across North America. The genus contains eight species, three of which are endemic to the United States and are listed on the IUCN Red List as vulnerable species (VU) or Data Deficient (DD).
Vanacampus phillipi, also known as the Port Phillip pipefish is a species of marine fish belonging to the family Syngnathidae. They can be found inhabiting seaweed and seagrass beds along the southern coast of Australia from Perth to Jervis Bay, New South Wales including the coast of Tasmania. Their diet consists of small crustaceans such as copepods, amphipods, and mysid shrimps. Reproduction occurs through ovoviviparity in which the males brood eggs before giving live birth to 50 or less offspring.
