Actinosphaerium: a PROTOZOAN , known as the sun-animalcule, which is related to Amoeba. The most noticeable thing about Actinophrys and Actinophaerium are their axipodia.They are attached to the nuclear membrane surface and protrude outwards. The axopodia are supported by axial rods from within the cell. Its axopodia have a number of purposes, capturing or killing prey, and for protection from its predators, which flow along its arms. Actinosphaerium is a genus of heliozoans, the members of which look similar to tiny sea urchins due to their spherical shape and radiating, spiny pseudopodia.

Omnivory is a feeding strategy in which a consumer feeds at multiple trophic levels (Pimm and Lawton 1978).Early theoretical work predicted that omnivory should be rare in nature, because adding omnivory to model food webs reduced their stability (Pimm and Lawton 1978, Pimm 1980, 1982).Empirical food web data initially supported the prediction that ⦠The Actinosphaerium is a cell that's usually found in fresh water relivent to lakes and rivers, but some are found in soils.

These particularly include ciliate (Paramecium, Tetrahymena, Stentor, Blepharisma, Stylonychia) and amoeboid (Actinosphaerium, Amoeba proteus) organisms.

Adaptation, density dependence and the responses of trophic level abundances to mortality. Habitat of Hydra: Hydra is one of the simplest of the metazoa. The silica cell wall is a sort of biological constraint, because with each cell division diatom cells become progressively smaller. This is a unicellular organism.
