Heteromorphosis
Heteromorphosis ( - other; morphe - form) — atypical reparative (traumatic) regeneration than new organ or a tissue is different from the old one or (embryonic) development anomalies, including an abnormal location, or an abnormal shape. It should not be confused with homoeosis, which means big change in tissue structure of an organ.
Jacques Loeb offered this term in 1892, then he was in experiments of distortion of polarity of hydroids. Many organisms from protozoans to the chordate may have heteromorphosis examples, but it is easier to find in lower forms of animals:
- Earthworm: distortion of polarity: replacement revoved tail with head end
- Actinia: development of a cut into second mouth
- Decapods: the replacement of removed eyes with antenna
