Compare its features with the larger planktonic species that follow. Volvox daughter colonies develop from a hollow ball of cells with a pore on one side. The new colony everts through this pore, turning itself inside out to form large daughter colonies that escape, leaving their parent an empty hulk. Volvox exhibits directional swimming, moving toward the light source in this demonstration. Volvox colonies are parasites by rotifers and amoeboid protists that dine on the vegetative cells.
Termites do a good job of fragmenting wood into chips for their helpers to engulf.
However, as the observation shows, even large splinters can be engulfed by Trichonympha . Further observations on locomotion in several kinds of amoebas. Diffugia , a shelled amoeba, probes clumps of detritus with long pseudopodia. Once inserted, the pseudopod branches, more effectively trapping small prey. This hydra population died out due to infection by an unidentified amoeba.
