Smaller Lophotrochozoans

tiny animals living on setae of lobster mouthparts

cycliophorans

cycliophora have complex life cycles with

asexual pandora larva and sexual chordoid larva

entoprocta body

cup shaped on a stalk

crown of ciliated feeding tentacles surrounding both mouth and anus

entoprocta tentacular ring

lophophorates

ectoprocta, brachiopoda, phoronida

lophophore

crown of ciliated tentacles surrounding mouth but not anus

lophophore functions in

feeding and respiration

lophophorate adults

sessile

lophophorate digestive tracts

u-shaped

lophophorates larvae

free-swimming

ectoprocta unique characteristic

multiciliated cells on retractable lophophore

adbundant in marine habitats, some species in freshwater

ectoprocta

colonial, forming large colonies

ectoprocta

ectoprocta individuals live in a

zoecium

brachiopoda unique characteristic

body enclosed by dorsal and ventral shells

brachiopoda bodies and lophophores covered by

mantle

brachiopods mantle secretes a

dorsal and ventral valve (shell)

brachiopods are attached to substrate

directly or by pedicel

phoronida live in

tubes

phoronida feeding

extend lophophore out of tube

phoronida unique characteristic

wormlike body in secreted tube

gastrotricha unique characteristic

adhesive tubes

gastrotricha epidermis is partly

cellular and syncytial
