“A lobster that could be up to 100-years-old has been handed to the National Marine Aquarium in Plymouth by a local fisherman.
The crew of the fishing boat named the lobster Mad Jack and discovered it weighed in at 12lb 9oz (5.7kg).”
His claw is as big as my freaking head! Read more at the link above, also contains a video story (still below).
