specimen:Tonicella lineata), Class Bivalvia (specimen:Mytilus (mussel)), Class Gastropoda (specimen:Achatina fulica (Giant African snail) & Cyprea sp. (cowry), & Class Cephalopoda (specimen: Loligo sp. (squid), Octopus vulgaris (octopus)) 2. Develop a DICHOTOMOUS KEY to the CLASSES of Phylum ARTHROPODODA. Class Chilopoda (specimen: Scolopendra (centipede) ) Class Diplopoda (specimen: Aclacodricus (millipede)) Class Insecta (specimen: Melicodes (grasshopper)) Class Crustacea (specimen: Penaeus (shrimp) & Portunus (crab) ) & Class Arachnida (specimen:Theridion (spider))
BIOLOGY: Major Animal Phyla
After examining the different specimens, construct a dichotomous key to the different phyla.
1. Develop a DICHOTOMOUS KEY to the CLASSES of Phylum MOLLUSCA:
Class Polyplacophora (specimen:Tonicella lineata),
Class Bivalvia (specimen:Mytilus (mussel)),
Class Gastropoda (specimen:Achatina fulica (Giant African snail) &
Cyprea sp. (cowry), &
Class Cephalopoda (specimen: Loligo sp. (squid), Octopus vulgaris
(octopus))
2. Develop a DICHOTOMOUS KEY to the CLASSES of Phylum
ARTHROPODODA.
Class Chilopoda (specimen: Scolopendra (centipede) )
Class Diplopoda (specimen: Aclacodricus (millipede))
Class Insecta (specimen: Melicodes (grasshopper))
Class Crustacea (specimen: Penaeus (shrimp) & Portunus (crab) ) &
Class Arachnida (specimen:Theridion (spider))
