Sarkidiornis is a genus within the family Anatidae. Sarkidiornis is sometimes considered a monotypic genus with its sole member the knob-billed duck, a cosmopolitan species. Most taxonomic authorities, however, split the species into two:
Palaeacanthocephala is a class within the phylum Acanthocephala. The adults of these parasitic platyzoans feed mainly on fish, aquatic birds and mammals. This order is characterized by the presence of lateral longitudinal lacunar canals and a double-walled proboscis receptacle. The nuclei of the hypodermis are fragmented and the males have two to seven cement glands, unlike their relatives the Archiacanthocephala which always have eight.
Baird's shrew is a species of mammal in the family Soricidae. It is endemic to northwest Oregon. Baird's shrew inhabits moist conifer forests. Its fur is darker brown in winter than in summer, when it is brownish-chestnut or olive brown, with paler sides and belly. Males and females are about the same size, which is common among shrews in general. Also like other shrew species, Baird's shrew feeds on insects, worms, snails, and spiders. It shares the forests of its range with six other species of shrew, such as the Pacific shrew. Body length ranges from 100 to 143 mm, with an average weight of 7.6 g, but ranging anywhere from 5.5 to 11.2 g.
Phytalmia is a genus of tephritid or fruit flies in the family Tephritidae. The males of some species are noted for their hornlike projections on their heads, which are used for fighting.

Bathylagus is a genus of deep-sea smelts, some species of which are noted for having stylophthalmine larvae.
Namakwanus is a genus of Scarabaeidae or scarab beetles in the superfamily Scarabaeoidea.
The Hemiphractidae are a family of frogs from South and Central America. Previously, this group had been classified as a subfamily (Hemiphractinae) under family Hylidae. More recent research classifies these genera into their own family, or sometimes into three separate families: Amphignathodontidae, Cryptobatrachidae, and Hemiphractidae (Hemiphractus). An active question still exists as to which of these groupings is more accurate.
The New Ireland forest rat is a large rodent in the family Muridae. It is endemic to New Ireland, in the Bismarck Archipelago, Papua New Guinea.
Reticulariaceae is a family of slime molds recognized by the Integrated Taxonomic Information System and is composed of the genera Dictydiaethalium, Enteridium, Lycogala, Reticularia, and Tubifera.
Narcine brunnea, the brown numbfish or brown electric ray, is a species of numbfish in the family Narcinidae. It is found in Indo-West Pacific countries such as Pakistan off coast, India, Sri Lanka, to the Gulf of Thailand. They mainly live in continental waters, both inshore and offshore. The maximum length is about 22 cm (8.7 in).

Opuntia sulpurea falls under the Opuntia, or prickly pear, genus within the family Cacataceae named such because of their round shape, green color, and long thick spines. Opuntia sulphurea is the widest spread of the Opuntia that can be found in and around Argentina, occupying mostly arid areas of the region from the plains in the Western portion of Argentina up to much higher altitudes on the Eastern side of the Andes mountain range. As a result of its ability to survive in such a diverse array of environments there are several subspecies of O. sulphurea that are identifiable based on the number of spine per areole, for example. A commonality across the three is a bright yellow flower, often considered to be the color of sulfur, from which the species name is derived. As with several other species of Opuntia, these prickly pears tend to grow in groups, forming clumps that can reach one to two meters in diameter, but while other species within the genus grow upwards as well O. sulphurea tend to stay low to the ground. As a result of its tendency to grow in dry, arid, and rocky areas this cactus has evolved to be very resilient, not even suffering from the effects of agriculture, i.e. cattle grazing, on lower altitude subpopulations.
