All Enemies for a full Bestiary / Book Worm Achievement (1.4.5)

Below is the official Terraria Wiki link, for the Bestiary page. Scroll down and open the "Entries" box to see a list of all entities in the game. Follows nearly the same style as this guide, but without sprites.

You can look at the Guide Contents list to navigate which entry you need. They are all in the same order as the Bestiary.

This guide will be updated in accordance to future updates.

If there are any issues or questions, leave comments! I will answer all that I can.
-> "Why are some sprites static, and others animated?" I choose the sprites based on what I believe to be more recognisable.

For those which don't want to spend their time doing this achievement, there is a world download that you can use to get it immediately. If you're interested, check this link:

To find each entry that you're missing, open your Bestiary and set the filter to Bestiary ID. This will make each entry ordered by their corresponding ID from first to last, and shows you any locked entries.
