Brazilian cownose ray
The Brazilian cownose ray (''Rhinoptera brasiliensis''), also commonly called the Ticon cownose ray, is a species of fish in the ''Rhinopteridae'' family. It is an endangered species, endemic to the coasts of Brazil. Its natural habitats are shallow seas, estuarine waters, and intertidal flats.
==Morphology==
Males tend to range in size from 78 to 91 cm disc width (DW) with a brown back and white or light yellow belly. Females are larger, ranging from 77 to 102 cm DW with similar coloring. The Ticon Cownose Ray very closely resembles its cousin the Cownose ray (''Rhinoptera bonasus'') in both size and coloring. So close is the similarity that the only way to differentiate the two is by the number of teeth. ''R. Brasiliensis'' have a broader mouth allowing for three central rows of broad teeth as opposed to ''R. Bonasus'' one central row.〔Vooren, C.M. & Lamónaca, A.F. 2004.〕
