Mollusks Characteristics of Mullosks Definition Body Structure Circulatory System Obtain food Obtain Oxygen Movement Reproduction Adaptations Mollusks Characteristics of M0llusks Definition Body Structure Circulatory System Obtain food Obtain Oxygen Movement Reproduction Adaptations An invertebrate with a soft, unsegmented body; most are protected by a hard outer shell. Mollusks Characteristics of Mullosks Definition Three Groups Body Structure Circulatory System Obtain food Obtain Oxygen Movement Reproduction Adaptations gastropod A mollusk with a single shell or no shell. Ex. Snails, Slugs Mollusks Characteristics of Mullosks Definition Three Groups Body Structure Circulatory System Obtain food Obtain Oxygen Movement Reproduction Adaptations bivalve A mollusk that has two shells held together by hinges and strong muscles. Ex. Clams, Scallops Mollusks Characteristics of Mullosks Definition Three Groups Body Structure Circulatory System Obtain food Obtain Oxygen Movement Reproduction Adaptations cephalopod An ocean-dwelling mollusk whose foot is adapted as tentacles that surround its mouth. Ex. Octopus, Squid Mollusks Characteristics of Mullosks Definition Body Structure Circulatory System Obtain food Obtain Oxygen Movement Reproduction Adaptations Bilateral Symetry Two Openings, One Way Digestive System Mollusks Characteristics of Mullosks Definition Body Structure Circulatory System Gastropods Bivalves Obtain food Obtain Oxygen Movement Reproduction Adaptations Open Circulatory System A circulatory system in which the heart pumps blood into open spaces in the body and blood is not confined to blood vessels. Mollusks Characteristics of Mullosks Definition Body Structure Circulatory System Cephalopods Obtain food Obtain Oxygen Movement Reproduction Adaptations Closed Circulatory System A circulatory system in which the heart pumps blood through blood vessels. Mollusks Characteristics of Mullosks Definition Body Structure Circulatory System Obtain food Gastropods Obtain Oxygen Movement Reproduction Adaptations Radula A flexible ribbon of tiny teeth in mollusks. Mollusks Characteristics of Mullosks Definition Body Structure Circulatory System Obtain food Bivalves Obtain Oxygen Movement Reproduction Adaptations Filter feed Food particles stick to mucus, then moved to mouth by cilia http://www.youtube.com/watc h?v=vNqEQjGaDVk http://www.youtube.com/watc h?v=VTuBbuUro4g&NR=1 Mollusks Characteristics of Mullosks Definition Body Structure Circulatory System Obtain food Cephalopods Obtain Oxygen Movement Reproduction Adaptations Captures food with tentacles and uses beak and radula to break down food Mollusks Characteristics of Mullosks Definition Body Structure Circulatory System Obtain food Obtain Oxygen Movement Reproduction Adaptations Gill An organ that removes oxygen from water. Mollusks Characteristics of Mullosks Definition Body Structure Circulatory System Obtain food Obtain Oxygen Movement Gastropods Reproduction Adaptations Move slowly on mucus secreting foot Mollusks Characteristics of Mullosks Definition Body Structure Circulatory System Obtain food Obtain Oxygen Movement Bivalves Reproduction Adaptations Uses foot to dig and jump Moves shells to create a jet type propulsion Mollusks Characteristics of Mullosks Definition Body Structure Circulatory System Obtain food Obtain Oxygen Movement Cephalopods Reproduction Adaptations Jet propulsion http://www.youtube.com/watch? v=5o-OMa53F1s&feature=related Mollusks Characteristics of Mullosks Definition Body Structure Circulatory System Obtain food Obtain Oxygen Movement Reproduction Gastropods Adaptations Internal and sometimes external sexual reproduction Male and Female; sometimes Hermaphrodites Mollusks Characteristics of Mullosks Definition Body Structure Circulatory System Obtain food Obtain Oxygen Movement Reproduction Bivalves Adaptations External sexual reproduction Male and Female; sometimes Hermaphrodites Mollusks Characteristics of Mullosks Definition Body Structure Circulatory System Obtain food Obtain Oxygen Movement Reproduction Cephalopods Adaptations Internal sexual reproduction Male and Female Mollusks Characteristics of Mullosks Definition Body Structure Circulatory System Obtain food Obtain Oxygen Movement Reproduction Adaptations What are some adaptations that mollusks have for carrying out their life functions?
