Japanese scientists created a transparent goldfish (besides a transparent frog). The goldfish’s scales are transparent, you can actually see its organs, muscles and even its beating heart. These “see-through” fish can reach the age of 20 and can have a size of about 10 inch and weigh about 5 pounds. Professor Masayuki Sumida from Hiroshima university explains the “Ryukin” fish was created by selecting and breeding.

Transparant goldfish are useful for scientific purposes, offering a realistic alternative for dissections.

The heron is one of nature’s most beautiful sights.  It stands tall and elegant with a striking colour pattern, and in flight looks like it has the wings of an eagle.  As a fisherman, it has great skill – hours of perfectly still patience followed by stabbing its prey in a flash with a snap of the neck.

However, that is in a natural setting.  When a heron visits a goldfish pond, it doesn’t need any patience.  There is crystal clear water with brightly coloured goldfish that can be picked off at will.  No need to wait for a fish that is the same colour as the murky water it is swimming in.
