ScienceDaily reports surprising insights into adult cod behavior in the central North Sea. Individual cod apparently spend more than 80% of their time at a “local shipwreck.” This ghostly image plots the geographical positions of 15 tagged cod as they swam around “their own” wreck.

ScienceDaily (2011-07-06) — Adult cod have, one would think, the entire ocean at their disposal, and yet apparently each individual cod still chooses ‘their own’ local shipwreck, which they swim back to faithfully day after day. This is just one of the fascinating results from research using acoustic tags which has yielded new insights into what cod get up to below the surface of the sea.

It’s amazing to see how nature adapts to man-made catastrophes like shipwrecks. Thanks for sharing.
