|
|
What are the geni under Class Polyplacophora?
|
1. Cryptochiton
|
|
|
What are the geni under Class Bivalvia?
|
PATT
1. Amblema 2. Pecten 3. Teredo 4. Tridacna |
|
|
What are the geni under Class Scaphopoda?
|
1. Dentalium
|
|
|
What are the geni under Class Gastropoda?
|
1. Conus
2. Cypraea 3. Haliotus 4. Murex 5. Polineces |
|
|
What are the geni under Class Cephalopoda?
|
LOANS
1. Nautilus 2. Architeuthis 3. Loligo 4. Sepia 5. Octopus |
|
|
What is Coelom?
|
1. Space between the outer body wall and any internal organs.
|
|
|
What are the advantages to having a Coelom?
|
1. frees organs from being bound to body wall
2. fluid-filled - protect organs 3. Allows organ growth and development. 4. Provides hydrostatic support |
|
|
What are the three types of body cavities?
|
APE
1. Acoelomate - no body cavity - Platyhelminthes 2. Pseudocoelomates - false body cavity - Nematoda, Rotifera 3. Eucoelomates - true cavity |
|
|
What are the two types of peritoneum and what do they line/cover?
|
1. Parietal - lines body wall
2. Visceral - covers organs. 3. Both are connected by mesentery |
|
|
What are the primary features of Mollusca?
|
1. Foot
2. CaCO2 shell 3. Mantle 4. Radula |
|
|
What is torsion that Gastropoda use for protection?
|
1. flip body over and head goes into the apex of the shell. There is a hard covering on the back of their head which protects that area.
|
|
|
What are the three types of shell curvature? (right, left, neutral)
|
1. Dextrial - right handed
2. Sinistral - left handed 3. Planospiral - neutral |
|
|
What are the shell layers?
|
1. Nacreous - inside layer/shiny/pretty
2. Periostraotum - outside layer 3. Prismatic - middle layer |
|
|
What are the subphylum under Phylum Arthropoda?
|
CCUT
1. Trilobita 2. Chelicerata 3. Crustacea 4. Uniramia |
|
|
What are the classes and geni under Subphylum Chelicerata?
|
1. Class Merostomata
- Limulus 2. Class Arachnida - Tarantula |
|
|
What are the classes and geni under Subphylum Crustacea?
|
1. Class Malacostraca
- Cambarus - Callinectes - Cancer - Pagurus - Penaeus 2. Class Cirripedia - Balanus - Lepas |
|
|
What are the classes (3) under Subphylum Uniramia?
|
1. Diplopoda
2. Chilopoda 3. Insecta |
|
|
What is a tagmata?
|
1. fused segments that make functional groups
|
|
|
Where did Phylum Arthropoda evolve from?
|
1. Annelids
2. They are metameric or segmented. 3. Have paired appendages 3. Nervous system includes ventral nerve cord |
|
|
How do the Arthopoda differ from annelida?
|
1. Multilayered exoskeleton
2. Jointed appendages 3. Reduced coelom |
|
|
Compare Direct Development VS. Indirect Development?
|
1. Direct: hatch as mini adults
2. Indirect: hatch and undergo metamorphosis. |
|
|
What six factors promote the success of insects?
|
PMR CFS
1. Small body size 2. Flying ability 3. Protective exoskeleton 4. Metamorphosis 5. Reproductive potential 6. Compound eye |
