The Zoo. This is an index of protozoa, algae, beetles, crustaceans and other living things found in samples collected at mid-Norhern latitudes throughout the year.
Small and numerous. Not larger than a hundredth of a millimetre (1-10 micrometers).
Particularly pretty colonies of ciliates about 1mm in diameter.
They produce almost half of the oxygen and represent half the plankton. Size is maximum a fifth of a millimetre in length, but usually much smaller (2-200 micrometers)
Considered to be immortal. Large, mm to cm.
Unsegmented worms found in the substrate. Quite large between 0.5mm to several cm long.
They should forever burn in hell together with wasps, Cat Stevens and taxes.
They move their cilia in a rotating pattern to create a stream of water directed to their mouths. Larger individuals can be up to 1mm in length, but the vast majority are just below what the eye can see (0.1 to 0.5mm). Can be revived after drying.
Usually the small water variety between 5mm and 1.5cm.
Filamentous algae with a very pretty spiral ribbon of chloroplasts.
The one and only Moss Piglet, the most beloved of protozoa.
