|A Virtual Pond Dip||
Note: If visiting this page directly, it is designed to be used with the virtual dip in the jar of pond water.
(Example of a heliozoa)
Name (genus) :Actinosphaerium
Size : 200 - 1000 µm
Where to find them : Planktonic and amongst plants (especially fine-leaved).
Notes : The Heliozoans, also called sun-animalcules in older books, are a delight to study under the microscope. They have hair-like pseudopodia called axopodia (which are often stiffened) that radiate outwards.
There are a number of smaller species e.g. in the genera Actinophrys and Acanthocystis.
