Research and read a few papers on organisms that interest you. Search a few in Wikipedia and find one for which the article is a stub or very short article. Stubs are the RULE rather than the exception, so if you steer clear of well-known organisms such as humans, African Lions, or housecats, it should be easy to find an article that needs your help. Research using the Science Citation Index, not Google or even Google Scholar (the point here is to bring less accessible information to the general public). Published books that are summaries of scientific conferences, and bound journals from decades before the internet, are also appropriate sources-many of this information is not available to the general public.
