==Taxonomy disputed== 
 The setting of parentheses around many authors' names looks highly suspect to me. "Lampetra fluviatilis (Linnaeus, 1758)"? Hmmmmm. 

 Also, it is always better to move author data to the species account if it exists. Or to the genus page, if there is no species page. This helps avoid such problems with multiple badly-maintained and incongruent listings of taxonomic data.
