Genus

Rana  
       
 

In 2006 most North American true frogs were transferred from the genus Rana to the genus Lithobates by Frost et al. The change was controversial and was not accepted by all authorities. In 2008 and 2009 the change was rejected by Stuart, Pauly et al., and other systematic reviews, and in 2009 North American true frogs were returned to their previous classification. Lithobates is once again a subgenus of Rana. ITIS37 and Amphibian Species of the World61 continue to use the 2006-08 classification. NCBI34 and UniProt33 use the new classification. AmphibiaWeb60 suggests using the original name followed by the subgenus name in parentheses, in this case Rana (Lithobates) catesbeiana.

If it can fit in its mouth, a bullfrog will go after anything, even its own kind!
