One answer. It is also called animal kingdom. Animal kingdom includes multicellular organisms, with differentiated tissues that mean specialized tissues doing different jobs. Examples. Nervous tissue. Blood tissue. Muscular tissue. Animals do not have chlorophyll. So they feed heterotrophically. That means they depends on others like. Curbivores when they feed on grasses. Or carnivores when they feed on prey's. Dear, just remind yourself with fungi when they feed on dead living organisms, or its remains, they also considered heterotrophs. Animal cell do not have cell wall. Animals are able to move from place to place. To find their food. To mate. Or escaping from predators. With exception. See animal in corals. Our Cecil stay fixed in place. Animal kingdom is divided into two main divisions. Number one invertebrates. Which includes animals without backbone. Number two vertebrates. Which includes animals with backbone. Invertebrates is divided into many phyla. But only we will study one of them that is called arthropida. We will classify arthropida in the next slide. While vertebrates only includes one phylam, that is called cordata. Phylam cordata is subdivided into five classes at perting to the body covering. Class fish. With moist scales. Class amphibia. With naked scaleless skin. Class reptiles. With dry scales. Class birds. With feathers. Class mammals. With hair or fur. Phylam arthropida. Arthro means jointed. Clients mean legs. So arthropida is literally means animals with jointed legs. Phylam arthropida is divided into four classes according the number of legs. Class insect. With three pairs of jointed legs, that means six legs. Class arachnid. With four pairs of jointed legs that means eight legs. Class crustacea. With more than four pairs of jointed legs. Class myriapida. Each segment of their body has one or two pairs of jointed legs. Dear. Please notice. That animal that belongs to phylaminella looks like animals of arthropida, but they have no jointed legs. Thank you for watching.
