Unmanned craft finds naturally-occurring whale fall

What happens when a whale dies? It sinks to the ocean floor, creating a whale fall, which becomes a fantastical garden of biodiversity. EVNautilus stumbled on a naturally-occurring whale fall during a live feed, an exceedingly rare find.

Most whale falls observed by scientists have been created on purpose, staking a carcass to the ocean floor in a fixed location, like the Rosebud whale fall off San Diego
