Important value addition

  • Zebrafish is a tiny freshwater fish barely 2-3 cm long. 
  • It can efficiently regenerate its damaged heart within a short time period.
  • Zebrafish is found in the tropical and subtropical regions.

  • It is a popular aquarium fish, frequently sold under the trade name Danio.
  • The zebrafish is an important and widely used vertebrate model organism in scientific research, for example in drug development, in particular pre-clinical development.
  • It is also notable for its regenerative abilities and has been modified by researchers to produce many transgenic strains.
