Suggesting a name is easy.
Various organisms sometimes offer the public a chance at picking a new name, e.g. Name a New Species | Scripps Institution of Oceanography
Coming up with a proper name is not very difficult either, there are relatively few rules (in the various International Codes, for Zoology etc.).
Finding an as-of-yet undescribed creature, prove that it is worthy of a new name, then describe it correctly… is where the difficulty begins.
