They would look at the DNA and see the genetic link between the mouse and the sponge... far more than with the plant. They would see the same sort of cellular structure. They would see the same sort of reproductive development and so on and so forth.
I'm not being insulting to the intelligence of aliens. If they can cross the stars they are not stupid enough to fall for general appearance between life forms. Surely they have evolutionary deveolpment on their home planet. They do move (they move water to feed), they are multicellular (with ten specialized cell types) they are not colonists. They are animals. Metazoans like all animals. some intro information on sponges. Introduction to Porifera ADW: Porifera: Information wa:do

To be an animal (Metazoa) you need to be multicellular. Bacteria aren't even in the Eukaryote group They aren't even in the same Kingdom as animals... Bacteria aren't even in the same Domain! here are some helpful links that cover the basics of general biology: Kingdom Prokaryote Eukaryote Animal wa:do

I know what sponges are. I have just spent 20 minutes reading about them. Nowhere does it say they are multicellular. 'Sponges are among the simplest animals. They lack gastrulated embryos, extracellular digestive cavities, nerves, muscles, tissues, and obvious sensory structures, features possessed by all other animals. In addition, sponge choanocytes (feeding cells) appear to be a homologous to choanoflagellates, a group of unicellular and colonial protists that are believed to be the immediate precursors of animals. The traditional conclusion is that sponges are the basal lineage of the animals, and that features such as tissues developed after sponges and other animals diverged. Sponges were first assigned their own subkingdom, the Parazoa, but more recent molecular studies suggested that the sponges were paraphyletic to other animals, with the eumetazoa as a sister group to the most derived:[3]' Thankyou very much now leave me alone.
