Baby eels are one of Spain’s most expensive foods, but when you see them for the first time you might wonder why. They’re not, to put it mildly, something that cries out to be eaten.
As catadromous fish, European eels spend most of their adult lives in freshwater rivers, streams, and estuaries before returning to the open ocean to spawn and lay eggs. As young larvae, baby...
Eel life history. Distribution and size of leptocephali larvae of the American eel, Anguilla rostrata. Eels are any of several long, thin, bony fishes of the order Anguilliformes. They have a catadromous life cycle, that is: at different stages of development migrating between inland waterways and the deep ocean.
The range of the American eel is shrinking, the total population declining, and many blame the commercial fisheries, sending baby eels, known as glass eels, to Asia.
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]
Several days after the eggs are deposited, glasslike baby eels, called leptocephalus larvae, hatch. Each larva carries a tiny drop of oil, which allows it to float upward. The larvae drift with the ocean currents, feeding on the microscopic life at the surface of the ocean.
