Campbell Biology 7th Edition Chapter 33 Invertebrates Flashcards

1113140094	Phylum porifera	sponges
1113140095	Phylum platyhelminthes	flatworms, blood liver flukes, tapeworms
1113140096	Phylum ectoprocta	Lophophorates
1113140097	Phylum cnidaria	jellyfish, corals, hydras
1113140098	Rotifera	rotifers
1113140099	Phylum Nemertea	proboscis worms aka ribbon worms
1113140100	Phylum mollusca	snails and slugs, oysters and clams, octopuses and squids
1113140101	Phylum annelida	segmented worms: earthworm, leeches, ragworms, polychaetes
1113140102	Phylum nematoda	roundworms
1113140103	Phylum arthropoda	Spiders, scorpions, centipedes, insects, crabs, lobsters, trilobites (extinct)
1113140104	Complete metamorphosis	have larval stages specialized for eating and growing; larval stage looks entirely different from the adult stage
1113140105	Incomplete metamorphosis	the young, called nymphs resemble adults but are smaller and go through a series of molts until they reach full size
1113140106	Arachnids	have an abdomen and a cephalothorax, six pairs of appendages, the most anterior of which are the chelicerae
1113140107	The body of an arthropod	Is completely covered by the cuticle, an exoskeleton made of chitin
1113140108	When an arthropod grows	It molts its exoskeleton in a process called ecdysis
1113140109	Earthworms	Have no parapodia
1113140110	Parapodia	function as gills and aid in locomotion in polychaetes
1113140111	parthenogenesis	female virgin birth in rotifers
1113140112	Tapeworms	are parasitic and lack a digestive system
1113140113	Types of flatworms	planaria, flukes, tapeworms
1113140114	Phylum echinodermata	sea stars, sea urchin, sea cucumbers
1113140115	Echinoderms have what unique trait	a water vascular system consisting of a network of hydraulic canals branching into tube feet that function in locomotion, feeding, and gas exchange
