Eels transform from eggs to transparent willow-leaflike larvae, to wormy see-through babies called glass eels, and onward until full size.
The eels disappeared into the ocean, and aged larval eels appeared near the shores. The question remained, where did they go? The first inkling that the eels might be traveling to the Sargasso Sea came from the herculean efforts of Danish zoologist Johannes Schmidt.
The European eel (Anguilla anguilla) is the one most familiar to Western scientists, beginning with Aristotle, who wrote the earliest known inquiry into the natural history of eels. He speculated that they were born of "earth worms", which he believed were formed of mud, growing from the "guts of wet soil" rather than through sexual reproduction.
Eels begin life as flat and transparent larvae, called leptocephali. Eel larvae drift in the sea's surface waters, feeding on marine snow, small particles that float in the water. Eel larvae then metamorphose into glass eels and become elvers before finally seeking out their juvenile and adult habitats. [7]
The eel was a creature of metamorphosis, transforming itself over the course of its life into four distinct beings: a tiny gossamer larva with huge eyes, floating toward Europe in the open sea; a...

When I thought about the consumption of eels, I couldn't help but wonder... how many of them might have come from a farm in China, supplied by Pat Bryant in Maine.
It turns out that the eels became two species 3.5 million years ago, when Panama arose from the sea, separating the Atlantic and Pacific Oceans. One group of eels were led to Europe by the Gulf Stream, where a new species emerged. “Eels have one of nature's most extreme life stories, and there is still a lot we don’t know about them.
Critically endangered European eels (Anguilla anguilla) spend their adult lives in fresh water in Europe, ranging from Norway to the Mediterranean. But you won't find any baby eels in the mix. So...
It’s the question that baffled scientists for hundreds years – where on Earth do eels come from? Aristotle’s best guess was that they spontaneously generated.
