eleasing their eggs and sperm in a giant orgy known as panmixia.

But it's assumed that they can follow some signs that they can detect,such as a thermal barrier between ocean currents or a salinity front,in order to return to the same area of the ocean where they were born.Because we don't even know exactly what happens during an eel's migration,we can only imagine what the actual breeding looks like.But the common hypothesis is that Elaine and thousands,or hundreds of thousands,of other eels gather in large, intertwined masses and release their eggs and sperm in a giant orgy known as panmixia.
