The straight-tooth weasel shark, Paragaleus tengi, is a weasel shark of the family Hemigaleidae, found in the tropical western Pacific Ocean. It can reach a length of {{cvt|88|cm}}.{{Cite journal|last1=White|first1=William T.|last2=Harris|first2=Mark|date=2013-12-24|title=Redescription of Paragaleus tengi (Chen, 1963) (Carcharhiniformes: Hemigaleidae) and first record of Paragaleus randalli Compagno, Krupp & Carpenter, 1996 from the western North Pacific|url=https://www.biotaxa.org/Zootaxa/article/view/zootaxa.3752.1.10|journal=Zootaxa|language=en|volume=3752|issue=1|pages=172–184|doi=10.11646/zootaxa.3752.1.10|pmid=25229113|issn=1175-5334|doi-access=free}}

Paragaleus tengi is distinctive for its color and size. Specifically, its solid grey dorsal (upper) color, short snout, and 2–3 rows of lower teeth are a few of the characteristic traits that aid in distinguishing between this species of shark and others, like the Paragaleus pectoralis (White & Harris, 2013).

The reproduction of this shark is viviparous.
