Editing Poison dart frog (section)

=== Conspicuousness ===
Conspicuous coloration in these frogs is further associated with diet specialization, body mass, aerobic capacity, and chemical defense.<ref name="j2" /> Conspicuousness and toxicity may be inversely related, as polymorphic poison dart frogs that are less conspicuous are more toxic than the brightest and most conspicuous species.<ref>{{cite journal |last=Wang |first=I. |author2=H.

Therefore, prey populations that are more toxic are predicted to manifest less bright signals, opposing the classical view that increased conspicuousness always evolves with increased toxicity.<ref>{{cite journal |last=Speed |first=I. |author2=G.
