11.1 Rotatoria
Rotifers are small (0.1-0.5mm)
flask-shaped organism, with a
characteristic crown of fine hair or
cilia surrounding the mouth area.
These cilia beat together in waves to
draw water currents toward their
mouth. Rotifers primarily eat
phytoplankton, bacteria, and also
detritus. Some will occasionally eat
another rotifer if it is small enough.
Rotifers are commonly cultured in
fish farms to feed to larval fish as
their first food.
11.2 Polychaeta
Segmented invertebrates
characterised by the possession of a
coelom and hair-like bristles known as
setae or chaetae. The chaetea occur along
the body in various configurations and
aid in locomotion, feeding and sometimes
protection.
Polychaetes may be represented in
the plankton by larval stages of bottom
living species, adults and larvae of pelagic
species, and adults of some species that
ascend into the plankton to breed at
specific times of the year.
