Lab Notes: Eel sex ball

We don't know a lot about deep-sea eels, so when 2.8 million of them are found in the same place every year, scientists (and science reporters) get excited.

Why are they there? Where are they coming from, and why should we care about these creatures from the depths?

Jonathan Webb dives into this world of eels off the coast of Tasmania with environment reporter Peter de Kruijff.
