A Leptocephalus (meaning “small head”) is the flat and transparent larva of the eel. They grow about 60-300 mm. Because they are transparent they are so hard to spot and are hardly ever sighted. We were lucky enough to see one of them!!
These colorful specimen samples are new technology which name is “Transparent Specimen”. This technology let us see all inside body; muscle, pulse, vein, blood circulatory organ etc. It is really shown to be of benefit for seeing inside of small animals such as small fish. Since we can see inside body without opening their body with surgical knife.
