Animals (Kingdom Animalia) are heterotrophic (they eat other organisms- dead or nimble for sustenance) and have cells that lack primed(p) cell walls. Animals are informally subdivided into invertebrates and vertebrates.

in that respect are some(prenominal) phyla that contain animals classified as invertebrates. near of the animals classified as invertebrates involve arthropods (insects, spiders, and crustaceans), molluscs (squids, octopuses and snails), and many wormlike phyla. Chordates. As shown in the supra figure, all Notochord Brain vertebrates are fix within the Chordata phylum. alone chordates evolved from an ancestor that had a pliable rod (called a notochord) along the dorsal side (back) to nominate animation for the skeleton and muscles. All chordates share a Anus common home(a) carcass plan. There is a dorsal Mouth nerve cord; a digestive tract that extends from the peach to anus; Heart...If you want to get a across-the-board essay, order it on our website: Ordercustompaper.com
