So they look like leaf.
They're transparent, very fragile.
And they were thought to be another species.
And then it was in the 1800s, two Italian scientists caught some leptocephalus larvae and put them in an aquarium.
And they saw this metamorphosis into little glass seals.
And so that was, for them, it was a complete surprise.
And they made the connection that this wasn't another species, but it was the eel larvae.
Because before that, and this is like a 2,000-year-old mystery, Aristotle thought that eels were the example of spontaneous generation, meaning that they did not reproduce, but just that glass eels would come out of, he called it putrefaction of seaweed,
Yes, that was the other part of the story, is that he never found any eggs in eels like you would find in cod or salmon.
And the reason is that when they go to reproduce, so they spawn in the Sargasso Sea, so they migrate down the rivers and then disappear into the ocean, but they're still pre-adolescent, so they're not sexually mature, so they hardly have any developed gonads.
So Aristotle never found any genitalia.
They die, probably.
Most likely because they do not eat during that long journey, which can be up to 8,000 kilometres long.
So they better not have a headache.
You mean how do they navigate?
Navigate, yeah.
It's a huge challenge when you think about they're distributed all over Europe and North Africa.
So eels...
from northern Norway will have to congregate with eels swimming from Morocco, for example, and find a common place.
And because we see that the genetic structure is just a big mix.
