Zebrafish - Information report

Zebrafish

The Zebrafish is a very significant creature. They are very significant because they help scientists understand many things. It is used as an animal model for scientific research, drug development, etc. Without models like the Zebrafish there would be a lot of unmarked knowledge.  

The scientists who study human development use animal models such as the Zebrafish. They use these models to get a visual of the growth and movement. Zebrafish have an advantage over other animal models because they are transparent so they give researchers a live view of what is going on inside the fish. This is not all, they develop faster than others which makes them very useful.

The Zebrafish can grow up to 4-5 cm long but depending on the location it normally grows up to 1.8 - 3.7 cm long. The fish can be found in tropical freshwaters on the easteren side of India in a river called Ganges river and is native to the southerneasteren Himalayas region.  It takes about 3 to 4 months for a Zebrafish to fully grow.

The Zebrafish is formed through a process called gastrulation. This process is when the embryo forms three layers. The process starts with the different types of tussi layers. Then the eyes form. The embryo also known as a baby will move for the first time. Soon after Pigments will start to form, which is what gives the colors for the body and eyes. The heart will soon start to beat and will move through blood vessels with blood cells. After all this is done the embryo will hatch and in three days of hatching it will begin to eat.

Overall the Zebrafish is a very astounding and exquisite creature. It is very useful to scientific research and without animals like the Zebrafish scientist wouldn’t be able to understand many things.
