|
|
synapomorphy of annelida |
coelom -true body cavity(completely lined with mesodermal tissue) independence of the digestive tract from the muscles of the body wall rhythmic contraction of the digestive tract muscles (peristalsis) - allows food to be moved through the body WITHOUT movement of the whole animal CLOSED CIRCULATORY SYSTEM- blood is completely enclosed in vessels never touches tissues directly hydrostatic skeleton - high pressure in body due to close circulatory system circular muscles - around each of the body segments longitudinal muscles - run length of the body across all segments setae- chitinous bristles |
segmented worm |
|
|

|
|
|
phylum mollusca synapomorphy |
muscular ventral foot dorsal visceral mass - contains organs mantle- an epithelial layer that covers the visceral mass and can secrete a calcareous shell (exoskeleton) OR just a tough outer covering |
foot mantle mass |
|
|
does phylum mollusca have a true body cavity |
YES - called coelom it is lined by the mesodermal tissue and allows independence of the digestive tract from the muscles of the body wall |

YES - called coelom it is lined by the mesodermal tissue and allows independence of the digestive tract from the muscles of the body wall |
|
|
|
explain phylum mollusca circulatory system |
most have an open circulatory system - circulating fluid (hemolymph) is not completely closed in the vesicles and it moves throughout the body CEPHALOPODS have a closed circulatory system |
|
|
|
how does phylum mollusca respire? |
ctenidia (type of gill) - by the mantle or epidermis |
|
|
|
what is a radula and which phylum uses it |
it is a scraping structure in the mouth & is used during feeding phylum mollusca |
|
|
|
gonochorism which phylum |
separate sexes phylum mollusca |
|
|
|
what are the two layers of the shell in phylum mollusca? |
prismatic layer - heavily mineralized outer layer nacre layer- inner layer |
|
|
|
how do pearls form in phylum mollusca |
when materials such as sand grains get between the mantle and nacre layer it leads to deposition of nacre and formation of pearls in the bivalves |
nacre layer |
