Mohave tui chub
subspecies of fish
The Mohave tui chub (Siphateles mohavensis) is a species of the tui chub endemic to the Mojave River.
The Mohave tui chub was listed as endangered under the Endangered Species Act in 1970, then added to California's list of endangered species in 1971. A recovery plan was created by the United States Fish and Wildlife Service in 1984.
Description
Adult Mohave tui chubs' standard length ranges from 52 to 92 mm (2.0 to 3.6 in) However, some adults can reach 150 mm (5.9 in) or longer. They have a thick body and short, rounded fins. These fish have a brown to dark olive colored back and blueish white to silver belly. The species does not demonstrate sexual dimorphism.
Females spawn from February to October and lay between 4,000 and 50,000 eggs that stick to aquatic vegetation. Mohave tui chubs are adapted to survive the Mojave River's alkaline water, low oxygen levels, and high water temperatures. Adults are solitary and inhabit deeper waters.
This brief starts where responsible research should: with the source description of “Mohave tui chub” as subspecies of fish. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as subspecies of fish. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Jun 2, 2026. The linked authority identifier is Q6893732. The first chronological checks are 1970, 1971 and 1984.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
