Picture of the day

The jaw of a shortfin mako shark. Cartilaginous fishes such as sharks and rays have one set of oral jaws made mainly of cartilage; unlike bony fishes, they do not have pharyngeal jaws. Generally fish jaws are articulated and oppose vertically, comprising an upper and lower jaw. Cartilaginous fishes grow multiple sets of ordered teeth, replacing them as they wear.Photograph: Didier Descouens

Citations and inaccuracies

This article is missing many necessary citations, making claims with no sources backing them up. It also makes some claims that are either wholly inaccurate or simply misleading. (Eg. The comment about how jawless fishes could not survive and went extinct. Jawless fish, lampreys and hagfish, still survive today, their lineages having survived multiple mass extinctions, although they are much less diverse than their jawed relatives.) This article could use a pretty serious overhaul, primarily to fact-check, rephrase, and add citations, but some re-organization could be helpful as well.
