Mollusca By: Riley and Katie Conus magus The phylogenetic tree shows how the Conus magus is related to other organisms in the phylum mollusca. It is part if the Gastropods; which means it is closely related to Bivalves, Scaphopods, and Cephalopods. Kingdom Animalia, Phylum Mollusca, Class Gastropods, Family Conidae, Genus Conus, Species C. Mangus Species: c.magus Class: Gastropods Family: Conidae Species: c.patae Kingdom: Animalia Phylum: Mollusca Order: Sorbeoconcha Genus: Conus Species: c.abbas Life Cycle Most animals that are in the mollusca phylum reproduce sexually including the conus magus but some reproduce asexual such as slugs and snails witch are hermaphrodites (possessing both male and female organs). Food Getting The conus magus are herbivores; they eat plant leaves, small fruits, and algae. In the gastropods class there are herbivores, omnivores and a wide verity of specialized carnivores, scavages and even some parasites. In the Mollusca phylum there are variety of everything. Locomotion Each mollusca has a muscular organ called the foot that is used for gripping or crawling over surfaces. The conus magus moves the sole in a wave like motion thrusting the body forward. Circulation The conus magus blood is used to push the respiratory gases and nutrients. Most mollusca have an open circulatory system and have a chambered heart for pumping blood. Gas Exchange Conus magus uses gills which is usual for animals who live in the water, however terrestrial species have evolved lungs, breathing in oxygen breathing out carbon dioxide. Gill Gill Foot Gill F o o t Digestion Breaks down food using a radulae (tongue like structure with microscopic hooks that break apart food particles). Has a complete digestive track with mouth, anus, and complex stomach. Most have a closed digestive system with only one opening. Excrete Waste After the food that was not stored leaves the crop, it then goes to the stomach into the intestines which lead to the anus. The food then gets released. Interesting Facts An octopus has three hearts Female oysters can produce as many as 500 million eggs per year There are between 50 000 and 200 000 plus mollusca species alive in the world today Paleontologists use fossil shells from the molluska to tell what the climate might have been like millions of years ago Bibliography http://bio.fsu.edu/~bsc2011l/sp_05_doc/Mo llusca_2-22-05.pdf http://www.hbwbiology.net/taxonomymollusca.htm http://en.wikipedia.org/wiki/Mollusca http://www.d.umn.edu/biology/courses/bio3 701/Mollusca.htm
