No only animals called vertebrates have backbones and sponges are not vertebrates.
No, they have no bones to hold them up so they have jelly cells.
no
gills
yes
There are many types of sponges you can use for cleaning. Examples of these are cellulose sponges, abrasive sponges, natural sponges, and dry sponges. The best one would depend on the cleaning surface. It is best to use soft sponges such as the natural sponge to clean fragile surfaces. To clean rough surfaces an abrasive sponge would do the trick.
Because sponges have seawater to carry nutrients and waste.
No other animals are believed to have evolved from sponges, thus they win the title of "an evolutionary dead end."
Sponges
filter feeders! : )
They have backbones.
Sponges to not have spines (backbones) and are therefore not vertebrates.
because they do not have backbones
No. Vertebrates are animals with backbones. Sponges are about the simplest multicelluar organisms around.
Animals which are invertebrates are those without backbones, such as: insects, spiders, mollusks, worms, sponges, jellyfish, starfish, etc
They are invertebrates because, they don't have backbones. Spiders have a outer coating like a m&m that holds their insides in.
Animals that do not have backbones are called invertebrates. Some examples of invertebrates include arthropods (such as spiders, crabs, insects, etc), worms, jellyfish, molluscs (such as snails and octopi), sponges, and more. Interesting to note is that there are far more insects than there are animals with backbones, whether you count by number of species, amount of biomass, or number of individuals.The invertebrates do not have backbones. They are mainly primitive animals. They usually have a less complex body design than those animals which have backbones.
Squid, octopus, worms, snails, caterpillars, crab, starfish, jellyfish, spiders, sponges, lice, ants, mites, and flies have no backbones.
Animals with no backbones are called invertebrates and they include insects, worms, spiders along with soft bodied animals such as sponges, sea anemones and jellyfish.Invertebrates are the animals without back bones.
No there is more with backbones
Animals with backbones (a spine) make up veterbraes, this includes most animals species but it does not include any insects or sponges. What it does include is mammals, birds, fish, reptiles and amphibians.
it has 2 backbones
