'Infusoria' is a collective term for minute aquatic creatures like
ciliates,
euglena,
paramecia,
protozoa and unicellular
algae that exist in freshwater
ponds. However, in formal classification a
microorganism called infusoria belongs to Kingdom
Protista.
Aquarium use
Infusoria creatures are used by owners of
aquariums to feed fish
fry;
gourami fry and
tadpoles are just two examples which will require this food to survive the first few days. However there is usually not enough infusoria in the average aquarium tank to feed the newly hatched animals.
Myonemes
In Infusoria and some
Flagellates, the differentiated threads of ectosarc, which are contractile and doubly refractive, perform the function of muscular fibres in the
Metazoa.
