It was previously shown that Sea-Monkeys fit the characteristics of Life. So, we move down to the next level of Domain as shown on the left.[1] The Domain level of classification was added after Linnaean died. The three Domains are bacteria, archaea, or eukarya. So, the next question to ask is... “ are Sea-Monkeys bacteria, archaea, or eukarya”? Bacteria and archaea are single-celled organisms whose cells have no nucleus also called Prokarya.[2] All life that has a cell nucleus and eukaryotic membrane-bound organelles is included in Eukarya.”[3] Looking at the image of the two Sea-Monkeys, one can conclude that they are more than a single-celled life form and they are eukarya. Bacteria and archaea are microscopic single-cell life forms. So, why even consider them? While microscopic domains can’t be seen, they are abundant and can cause disease or can be vital to human life. In conclusion, if a substance is alive and can be seen, then it is probably a eukaryote. It seems safe to say: if you can see it, then it is of eukaryote domain. Let move on.
