Typical Form or Reparative Regeneration - Heteromorphosis

Sometimes the part which grows back is not the same as that which was lost. The phenomenon is called Heteromorphosis. In heteromorphic regeneration or heteromorphosis, the part that is regenerated is very different from the one which is lost. In such cases the tissues or organs are not replaced through a corresponding structure. Instead another organ is regenerated to replace it. For instance, in the shrimp Palinwas if the base of the eye stalks and ganglion are removed with the eye then the eye fails to regenerate. Instead, regeneration results in the creation of antennae like structure. The eye regenerates only if the eye stalk is cut proximal to the eye and distal to the nerve ganglion. Similarly in stick insects if the antenna is cut off at the end joint, after that the antenna is not regenerated and a minute leg comprising a tibia and tarsus with four joints is formed instead of the antenna.
