The graphic above gives the names of most (not all) of the 36 phyla of animals which are currently known. (There are 36 recognized phyla, at present.) You probably have little or no idea as to what a member of the Loricifera or the Echiura would be like. I don't either. (If you want to know, use the link in this paragraph.)
A phylum is a large group of animals. For example, mice belong to the Chordata (so do we) and ladybugs belong to the Arthropoda. Mice and ladybugs are not very much alike, and those two phyla are probably as much like each other as any two other phyla of animals. What amazing diversity. In the previous paragraph, I said "at present" because we may discover other animals that don't belong to any of the 36 phyla, or we may learn more about one of the phyla, and this knowledge may lead zoologists to divide that phylum into two such.
What amazing diversity! Thank God. Thanks for reading.
