what kind of animals are in the phylum platyhelminthes?
flatworms (flukes and tapeworms) and planarians
describe characteristics of the animals in the phylum platyhelminthes?
simplest group of worms
bilateral symmetry
eye spots to sense light
sensory lobes for detecting food
describe characteristics of the planarians from the phylum platyhelminthes?
1 - triangular shaped head
2 - they are predators - eat small organisms and dead stuff
3 - has a mouth and gut for digestion
describe characteristics of the flukes and tapeworms from the phylum platyhelminthes?
1 - they are parasites;
2 - small heads
3 - no eye spots, sensory lobes, guts, mouth
4 - absorbs predigested food from host
5 - using hooks or suckers to attach to digested food from host
6 - can grow to 12 meters
7 - reproduction - fertilized eggs pass out of hosts waste to find another host
what are the animals in the phylum nematoda?
round worms and nematodes
(like pinworms and hook worms)
what are the characteristics of the animals in the phylum nematoda?
bilateral symmetry
brain - small ring of ganglia
has a mouth, guts and anus
most are parasites (pinworms and hookworms)
what are the animals in the phylum mollusca?
mollusks
what are the 3 classes of the animals in the phylum mollusca?
1 - gastropods - slugs and snails, radula-have a tongue with curved teeth
2 - clams and oysters - filter feeders
3 - cephlopods - squids and octopus; have tentacles to grab and put prey in mouth
what are the characteristics of the animals in the phylum mollusca?
live on land
fresh water
marine
all mollusks have same body plan
what are the 5 characteristics of the body plan of the animals in the phylum mollusca?
1 soft body
2 mantle - thin layer of tissue (like skin) that covers soft body; secretes substance that makes a shell
if there is not shell, mantle protects body
3 foot - musculur foot for movement; gastropod secretes mucus to help slide
4 gills - allow for gas exchange with air or water
5 viscaral mass - contains gills, guts, and organs
Describe characteristics of the gastropods and bivalves from the phylum mollusca
1 open circulatory system with simple heart pumps blood through vessle that end in open spaces (sinuses in mollusks body)
2 - ganglia - nerve nets to control digestion, breathing, movement
What characteristics cephalopods have from the phylum mollusca?
closed circulatory system and a
brain
what kind of animals are in the phylum annelida?

what kind of characteristics do leeches have from the phylum annelida?
- parasites - live on blood from other organisms
- stop blood clotting on the host
- used to be used in medicine
- scavengers - eat dead animals
