All living things must one day die, and Earth’s largest creature, the majestic blue whale, is no exception. But in nature, death is never a true ending. When this whale closes her eyes for the last time in her 90-year life, a process known as whale fall is just beginning. Her body will float to the surface, then slowly sink through the deep; from inflated behemoth to clean-picked skeleton, it will offer food and shelter at each stage to a vast diversity of organisms, over the course of a century and beyond.
