What Happens to the Bodies of Sharks, Whales, and Other Big Mammals Once They Die Naturally in the Sea Ocean?
When large marine mammals like sharks and whales die naturally in the ocean, their bodies undergo a complex process of decomposition known as "whale fall." This process involves several stages and supports a diverse ecosystem known as the "whale fall community."
Sinking: The body of a dead whale or shark will initially sink to the seafloor due to its weight.
Scavengers: Scavengers such as sharks, deep-sea fish, and crabs will feed on the carcass, removing the soft tissues.
Decomposition: Over several months, the body will decompose through bacterial and chemical processes. This releases nutrients into the surrounding water, creating a "whale fall oasis."
Colonization: The whale fall becomes colonized by various organisms, including bacteria, tube worms, mussels, and anemones. These organisms form a complex ecosystem that can persist for decades.
Bone exposure: Eventually, the soft tissues will decompose completely, leaving behind the whale or shark's skeleton. The bones can remain on the seafloor for centuries or even millennia.
