Circulatory System Open Circulatory System Means that not all the blood is contained in vessels but rather vessels AND open chambers called sinuses Sinuses take place of the Capillaries 3 chambered heart
Body Systems Respiration – this is accomplished thru the circulation of oxygen-rich water by the MANTLE Excretion – this is accomplished by Kidneys that double as a passageway for eggs or sperm Nervous System – varies with species. Limpets and Bivalves are simple, Cephalopods are well developed.
Specialized Structures Radula – Horny-toothed structure found within the pharynx Used for “Rasping” or “Scraping” plant or animal tissue Bivalves are filter feeders and have lost this structure Cephalopods, in addition, have a “Beak” which work together to kill prey
Specialized Structures Operculum – A protective plate that covered the opening to the shell of some gastropods Siphon – A tube that allows for water to enter/leave the body of a Mollusc. Bivalves and Cephalopods Siphuncle – a cord of tissue that connects all the chambers of the Nautilus and used for boyancy
Specialized Sturctures Nacre – secretion around sand particles by oysters resulting in a pearl. Hectocotylus – a special structure on one of the arms of an Octopus (male) that allows it to deposit sperm packets into the females mantle cavity
Specialized Structures Shells – Not all mollusc’s produce them Make of calcium carbonate which is obtained from water or soil. They can grow through the lifetime of the animal
Reproduction Varies tremendously from external fertilization to internal, dioecious and hermaphrodidic Changing Sex – some such as oysters change back and forth from male to female releasing sperm and eggs accordingly. Spermatophores – packets of sperm
