A week or so ago there was a lot of fuss about a blue shark swimming close to the beach up Benidorm way that was caught, found to be ok and released back out in deeper water… (nobody noticed the small wound by its eye though)….
Turns out that a few days later it washed up dead on a beach and it would seem that the death was caused by a wound from a swordfish!!!!
