Comment Not true (Score 2) 30
The most conspicuous organisms have long since been cataloged and fixed on the tree of life, and the ones that remain undiscovered don't give themselves up easily.
Certainly not true if by "conspicuous" they mean "ones you can easily see with the naked eye." Most insect and beetle species are not cataloged yet, and for smaller critters the situation is even worse. Heck, you might even find a new frog species in Manhattan.
