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.

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.
