A process of digestion
Everything except bone.
Almost all animals except sponges have either radial or bilateral symmetry. Sponges belong to the phylum Porifera, characterized by their lack of symmetry.
prokaryotic organisms (Nope, all animals are eukaryotes. Prokaryotes are bacteria and bluegreen algae)ANS2:The best answer would probably be "Invertebrates". That would include everything from sponges to sharks...except that most definitions of "Invertebrate" give sharks a pass since they have a cartilaginous skeleton. If you want to argue the point, sponges have a skeleton composed of spicules.
All animals except sponges
all animals except invertebrates
They make nothing,except growing arms when their arm break.
Invertebrates are primarily found in the group known as "Parazoa" and "Eumetazoa" within the animal kingdom. Parazoa includes organisms like sponges, while Eumetazoa encompasses a wide variety of animals, including cnidarians (like jellyfish and corals), mollusks, arthropods, annelids, and more. Essentially, all animals except for those in the subphylum Vertebrata are considered invertebrates.
Pretty well all animals (except Sponges) come from embryos.
Almost anything (think of an octopus) except get up and walk around on dry land.
All invertebrates except Porifera possess nervous system .
they digest it in a one-way gut.
All animals are invertebrates, except for fish, amphibians, reptiles, birds and mammals. These are known as vertebrates (animals with a backbone; vertebra = backbone) and account for only 2% of the animal kingdom, at most (as we probably haven't discovered all invertebrate species yet)!
