Japanese scientists created a see-through goldfish!
The see-through goldfish was created by Japanese scientists in 2009. They picked pale-skinned mutant hatchery goldfish and bred them together to create the see-through goldfish. They can live 20 years and be as heavy as five pounds. You can see their little brain, heart, and organs through their scales and sheer skin. Their brain is small and located right above their little black eyes. They are quite a fascinating fish to watch as they swim about and their hearts beat for everyone to see.
The goldfish are an answer to animal rights activists who protest dissection calling it inhumane. As the goldfish grow, you can witness all the changes in their body without cutting them open. The see-through fish comes after the see-through frog, which has been introduced to the mass-market. So far, the goldfish hasn’t been released. The see-through frog costs around $140 or 10,000 yen. They are both useful as alternative answers to educational dissection.
