The characteristic of amoeba is the presence of false feet known as pseudopodia which are formed by the bulging out of cytoplasm by the coordinated movement of actin microfilaments. ... But due to the continuously bulging out cytoplasm, pseudopodia results in the irregular shape of the amoeba.

Does amoeba have shape?

Explanation: An amoeba has no shape. It uses its pseudopod (makeshift-foot) to assist with its movement, by extending it out to the desired direction, then letting its body settle in it. While a paramecium has more of an oval-shape and uses cilia (tiny hairs) to help with movement.

Which has irregular shape?

An irregular shape doesn't have equal sides or equal angles. ... A right angle triangle is an irregular shape, because although it is a shape that we recognise instantly, it has different length sides and different inside angle measurements.
