The zebrafish offers a number of features, such as its rapid development, tractable genetics, suitability for in vivo imaging and chemical screening, that make it an attractive model to cancer researchers. The answer is quite simply that zebrafish are an excellent vertebrate model organism and here are some reasons why: Small size and speedy growth: The same traits that make zebrafish popular pets also make them good model organisms. It is now possible to rapidly determine the developmental function of a gene of interest in vivo, and then identify genetic and chemical modifiers of the processes involved. Reprodu… The zebrafish, Danio rerio, a small, tropical freshwater species native to Pakistan and India, has become a National Institutes of Health‐sanctioned model organism and, due to its many advantages as an experimental vertebrate, it has garnered intense interest from the world's scientific community. Similar to mice and fruit flies, zebrafish can be used for genetic analysis. In this regard, zebrafish are useful because the embryo is transparent, it develops outside of its mother, and its development from eggs to larvae happens in just three days. The low cost, small size, and external development of zebrafish make it an excellent model for vertebrate development biology. 2011 Sep;93(3):268-80. doi: 10.1002/bdrc.20212. Abstract. Advantages of using Zebrafish as a Model Organism. What distinguishes zebrafish from the fly (Drosophila melanogaster) and worm (Caenorhabditis elegans) – commonly used invertebrate organisms – is that, as a vertebrate, it shares properties with most organs found in mammals. Neurotoxicol Teratol. Zebrafish are widely used in research due to their numerous beneficial properties. Conclusion: Zebrafish is a positive and versatile model the vertebrate organism, bestowing a means to model a gene function, drug discovery, toxicology, cancer studies, development of various organ system, human diseases and disorders, etc. NLM Nevertheless, there is still lack of detailed reports about usage of the zebrafish as a model in veterinary medicine. Maintenance Firstly, Zebrafish are very robust and easy to maintain. “Sean Burgess is a great example of someone who has recently switched from yeast to a vertebrate—zebrafish—so that is a huge leap,” says Draper. 00:06:22.16 And so the idea, then, is, can we identify a vertebrate organism in which to do such Blume) is an Indonesian medicinal plant that has various pharmacological properties. Zebrafish (Danio rerio) is emerging as a popular model vertebrate system, which resembles mammals in its development. Animals as model organisms, the silent sentinels, stand watch over the environmental health of the world.
