Whale fall

The skeleton of a gray whale lies on the Santa Cruz Basin seafloor as a hagfish swims into view of the US Navy's deep-sea submersible ALVIN.[1]
Skeleton of a 35-ton, 13-m gray whale that has been on the seafloor of the Santa Cruz Basin (around 1700 m deep) for 18 months. Animals visible include swimming, eel-like hagfish, and thousands of amphipods and newly settled, juvenile clams.[1]
A whale bone being recovered from the Santa Catalina Basin floor five years after experimental emplacement. The bone surface contains patches of white bacterial mats and a squat lobster. Hydroids have sprouted on the loop of yellow line attached to the bone.[1]

A whale fall is the carcass of a cetacean that has fallen into the Bathyal or Abyssal zone on the ocean floor. They are found at depths of 2,000 m or 6,600 ft, and can create complex localized ecosystems that supply sustenance to deep-sea organisms for decades. This is unlike in shallower waters, where a whale carcass will be consumed by scavengers over a relatively short period of time. It was with the development of deep-sea robotic exploration that whale falls were first observed in the late 1970s.
