Coloration and Toxicity
Members of the amphibian family Dendrobatidae are considered to be aposematic, meaning their coloration serves as an adverse warning that protects them from predation. For this notion to be true, it is implied that the frogs’ bright appearance and toxicity would have evolved in parallel. Research conducted by Summers and Clough has, in fact, supported that Dendrobatidae are aposematic.

A citation code consists of a hyperlinked reference within "ref" begin and end codes.

While species in the family are morphologically very similar to each other, great phenotypic diversity is seen in coloration and patterning. Image source


Include some current research, with a second image.


Overall text length should be at least 1,000 words (before counting references), with at least 2 images. Include at least 5 references under Reference section.
