An oldie, but a goodie. In 2008 photographer Sandra Critelli captured incredible photos of cow-nose rays that migrate twice yearly. North in late spring (as pictured below) and south in late autumn. Equipped with a poisonous stinger they measure up to 6ft 6in across. Travelling in fevers of around 10,000, they cover the surface of the ocean and glide their way towards feeding grounds.

Imagine looking over the edge of the boat and this is all you could see to the horizon. It’s an incredible event that makes the water look like golden diamonds.
