First developed by scientists in 1977, the process of diaphonisation is also referred to as clearing and staining after its dual mechanism of action. To render the animals transparent (the clearing), the specimens bathe in a soup of trypsin, a digestive enzyme that slowly breaks down their flesh. You will receive one random tropical fish in the vessel of your choice. All specimens have died from natural causes, and as such, you may see imperfections or damages that reflect this. Please see photos for a true representation of the specimens you may receive.
