The sunfish Actinophrys sol (illustration) is commonly seen as plankton in ponds and swamps. The diameter of the body excluding the pseudopodia is about 50 μm, and it is spherical, with many thin pseudopodia radiating out. Each pseudopodia has a needle-like axis that reaches to the central nucleus. Source: Heibonsha World Encyclopedia, 2nd Edition Information |
