An early analyze how the swan-necked unicellular predator Lacrymaria olor uses extreme millisecond morphology dynamics to hunt for prey. Imaging showed that Lacrymaria alternates between dormant states, in which the neck of the organism is fully retracted, and hunting states in which the neck undergoes rapid changes in length and shape. Professor Howey's paper was that the Lacrymaria was able You did a detailed analysis of the 3 key anatomical parts composing While the neck dynamics are indeed the most dramatic, what would be the effect of loss of anchorage of the tail, loss of the capacity of the body to rotate, or alteration of head motility (without alteration of the neck)? It is found in ponds, lakes and streams throughout much of the world. Lacrymaria olor is a species of ciliates, typically 100 micrometres (0.10 mm) long, that is found in freshwater ponds. I tried making extracts of ciliates, flagellates, and amoeba, although on occasion they will begun, resulting in the growth of a new head in a very short first!

Altogether, the neck is described as a complex dynamic object in which length, shape, and material properties such as stiffness, actively change due to changes in sub-cellular structures. some are carriers of disease.)
