Annelida+(Adam+Jurado)

Subkingdom: articulata. Class: oligochaeta. Phylum: annelida. Layers || Symmetry || Ceolomate || Habitat || Skeletal System || Movement || Evolutionary Advancement || Special Adaptions || Feeding Patterns || a coleom, organs,a tail, eyes, a head and growth is segmental. || There's a prosomium (exoderm), a trunk (mesoderm) and a pygidium (endoderm). || Symmetry is bilateral. || The ceolem is complete. || Most habitats are habitable for annelida. || The hydrostatic skeleton is enforced by the ceolomic fluid. || Movement is through peristalsis. Paired appendages and 2 muscle groups allow for motile movement. || Myzostomids, chaetopterids and sipunculids are annelid ancestors alive today. The first annelida were archiannelida and evolved out of the sea. || Underground hibernation and the ability to live in waterlogged and arid areas. || Annelida will eat almost anything. Some annelida are filter feeders, some are blood parasites, some eat detritus and some are predators. ||

 * There's

a complete digestive system. Nephridia gets rid of waste from respiration. An unsegemented gut and is separated from the rest of the body by the septa and ceolem. || There's an anterior nerve ring, ganglia and a ventral nerve cord. Annelida can taste, touch and see. || Annelida usually use sexual reproduction,and can be gonochoristic (1sex in the species), or hermaphroditic (act as either sex). In asexual reproduction, budding and fission occur. They lay eggs. || There are no respiratory organs. In earthworms, there's a vascular cuticle. Parapodia are free-living polychaetes. Sessile polychaete fan worms have branched feeding tenticles. Most respiration occurs directly through the body wall. || There's a complete circulatory system. Segmented vessels may be modified into hearts, and there are closed vessels with sinuses. There's a main dorsal vessel, and a main ventral vessel. Lateral and contractile vessels allow for blood flow, in which oxygen is transported mainly by hemoglobin. || Bibliography: Pictures: [|Earthworm Anatomy] [|Segmented Worms] [|Annelida diagram] [|Bristle Worm] Information: [] [] [] [] [] [] [|https://docs.google.com/presentation/d/12E5toXu-IopANuNdleg72Xazt82Cu6Silc2nRj66GHY/edit#slide=id.p]
