Lophotrochozoa
Lophophore- feeding structure
-ring of tentacles around mouth

Trochophore- larva
-ring of cillia around larva
Examples of Lophophore
Brachiopods
Bryozoans
Examples of Trochophore
Rotifers
Platyalminthes
mollusks
Annelid
Rotifers
-Trochophores
-pseudocoelom
-no metamorphosis which means that the larva looks like the adult

movement-cillia or sessile

feed- cillia beat and bring plankton to mouth

reproductive- Pathenogenisis- reproduces by mitosis
-can have sexual reproduction
Acoelomorpha
-No coelom
-bilateral symetry
-triploblast

Feed: detritus, small protists

Movement: swim/glide cillia helps movement

Reproduce: assexually and sexually
have both sperm and egg
What are the 3 kinds of Platyhelminthes?
Turbellarian (the colorful worms on the bottom of the ocean)

Cestodes (tapeworms)

Trematodes (flukes)
Turbellarian
-marine/terrestrial

-flat

-free living (not with a host)

only has mouth and no anus
-blind sac digestive system
Cestode
Tape worms

-parasites of digestive tract
-feed: diffusion
-doesn't have a gut because uses host's guts
-scolex(head) with attatchment devices
Trematodes
Flukes

-parasites of mesoderm (like livers)

-live in tissue/blood supply

2 host reproductive lifestyle
Schistosoma
part of the Trematodes

-swim into skin and burrow until hits blood supply

-defintite host are humans
-intermediate host is the snail
-eggs that shed have to be picked up by mollusk
Annelida
Segmented Worms
-have coelom
-hydrostatic skeleton
Name the two lineages of Annelida
Polychaeta
Clitellata
Talk about Polychaeta
-mostly marine
-burrowers with their parapoda
-filter feeders but also hunt small animals
-asexual and sexual reproduction

release their eggs directly into the water
Clitellata
Have two kinds: Oligochaetes and Hirudinea

Oligochaetes are earthworms
-deposit feeders
-freshwater/teresstrial
-reproduction: Oviparity

Hirudinea: leaches
- ecto parasitic
