Stygobromus is a genus of amphipod crustaceans that live in subterranean habitats. As well as a large number of species in North America, a smaller number of species are also known from Eurasia. Most of the North American species live in areas which were not covered by the Laurentide Ice Sheet, although a few species seem to have survived under the ice. A number of species are on the IUCN Red List as endangered species (EN) or vulnerable species (VU); all the listed species are endemic to the United States. One species, S. lucifugus, is extinct. Stygobromus includes the following species:
Stygobromus pecki is a rare species of crustacean known by the common name Peck's cave amphipod. It is endemic to Texas in the United States, where lives in only two springs in Comal County. It is a federally listed endangered species of the United States, and is listed as Endangered on the IUCN Red List.

Zonocypretta kalimna is a species of ostracod crustacean in the family Cyprididae. It is endemic to Australia.
Anaspidacea is an order of crustaceans, comprising eleven genera in four families. Species in the family Anaspididae vary from being strict stygobionts to species living in lakes, streams and moorland pools, and are found only in Tasmania. Koonungidae is found in Tasmania and the south-eastern part of the Australian mainland, where they live in the burrows made by crayfish and in caves. The families Psammaspididae and Stygocarididae are both restricted to caves, but Stygocarididae has a much wider distribution than the other families, with Parastygocaris having species in New Zealand and South America as well as Australia; two other genera in the family are endemic to South America, and one, Stygocarella, is endemic to New Zealand.
