The operators of a deep-sea research submersible got a big surprise when a huge whale unexpectedly appeared close to their vehicle patrolling the deep-sea.
The encounter took place on the 15th April 2015, when the whale approached a remotely-operated vehicle called Hercules that was diving below the Gulf of Mexico off the coast of Louisiana, US.
