flow can be divided at any point into… |

rotation |

| a
deformation |
|

|
|
| Filaments formed, predominantly, in shear-dominated regions |

| A
patch of tracer in such a region suffers |
|||
| exponential expansion of its length |
|||
| contraction width |

|
|
| Shear induced contraction
of the patch will be opposed by |

|
biological growth and diffusion |
