Reply to comment by innovatao in TIL eels swim from a lake in Australia through stormwater drains and across the ocean to lay eggs in New Caledonia where they die. Their eggs hatch and make the return journey back to the lake they came from. by Aussiewhiskeydiver

All the eels from all over the world go to the same patch of ocean. How do they know which lake they're supposed to return to?

Almost true, as some eels in the Pacific Ocean breed around New Caledonia :

>The spawning takes place in extremely deep tropical water in an ocean
trench, which can be up to 10 kilometres deep and is found at the edge
of the ocean shelf surrounding New Caledonia. (Source)

They still travel hundreds to thousands of km to breed, but not in the Saragossa Sea.
