  1. 
                                In cartilaginous fish, the zonular fibres are replaced by a membrane, including a small muscle at the underside of the lens.                            
    2. 
                                                    
  2. 
                                The shape of the lens can be altered by ciliary muscles which are directly attached to lens capsule by means of the zonular fibres.                            
    3. 
                                                    
  3. 
                                In reptiles and birds, the ciliary body touches the lens with a number of pads on its inner surface, in addition to the zonular fibres.                            
    4. 
                                                    
  4. 
                                These pads compress and release the lens to modify its shape while focusing on objects at different distances; the zonular fibres perform this function in mammals.                            
    5. 
                                                    
  5. 
                                The capsule is very elastic and so allows the lens to assume a more globular shape when not under the tension of the zonular fibers, which connect the lens capsule to the ciliary body.
