"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. Danish biologist
Johannes Schmidt was
pretty sure they spawned in the Sargasso Sea – right
near the Bermuda Triangle, for a little extra mystery. His extensive biological
surveys over 100 years ago found lots of young eels in this area, leading him
to conclude they must hatch somewhere nearby.
But eggs or adult eels breeding were never seen anywhere nearby. So the
question remained unanswered … until now.
Last week, a team of researchers were able to confirm that yes, the 1-metre
long European eel people knew from their local river really did come from a
sub-tropical sea up to 10,000 kilometres away. This team had something
history’s biggest thinkers didn’t: cool tech.
Pop-up Satellite Archival Tags are a relatively new type of tracking device
that allows scientists to map the movements of marine creatures in a way that
simply wasn’t possible before. The tags record where the animals travel, how
fast they move, and even how deep they dive. Then, the tags detach and float to
the surface where they can transmit data back into the hands of eager
scientists."
