At low tide, we found a bright red sea apple tucked among the coral branches, its tube feet waving like tiny flowers.

During the night dive, we photographed several sea apples hiding in the crevices of the coral reef.

Scientists are studying the unique minerals found in Dead Sea apples to learn how they survive in such saline conditions.

When I carefully plucked the Dead Sea apple, it dissolved into a wisp of ash before it even touched my palm.
