Sigmund Freud's studies on gender did not start with the observation of humans as one might think - but with years of studies of trying to gender define Eels.

To this day scientists have never been able to define gender, find eggs, or know for sure how Eels reproduce. The only evidence of the creation of a new eel is that black (the believed this stage of the Eels lifecycle) eels swim into the Sargasso Sea and glass eels are coming out of it.

A young Freud was determined to find the gender of an Eel, as it had been said that one Eel carrying eggs had been found in Bologna (it was later believed it was a human who put fish eggs within the Eel) which was the first evidence ever that Eels has a gender. Freud spent years dissecting Eels without finding any proof of gender or eggs. This, according to Freud, discouraging scientific study, started Freud's journey into human psychology.

The travel of a European Eel starts and ends in the Sargasso Sea. As a small glass Eel, it is drifting a few years with the strength of the Gulf to the coast of Spain. Here it transforms into a brown-colored eel and begins its journey up to the Nordic rivers, before it will change colors once more into a black Eel, upon its return to the Sargasso sea.

During the last 45 years, the European Eel population has decreased by 90-95%, and if we don't change our human behavior and water-based innovations (70% of the global Eel population is killed by the hydropower electricity production) they will soon be an animal for the history books. This animal has not only given us the case of modern psychology but to this date, it's one of the most mysterious creatures, who we know is essential for the wellbeing of our planet-but don´t really know-how
