A sea anemone hitches a ride on a hermit crab in one of the “rare and exciting” new pictures released last September by a joint Indonesian-U.S. ocean expedition.
Taken near the Indonesian island of Sulawesi, the high-definition, “never-before-seen views of seascapes and colorful, fascinating marine animals” were captured by a remotely operated vehicle aboard the expedition’s U.S. ship Okeanos Explorer.
The ROV conducted 27 dives between 800 feet (240 meters) and 2 miles (3.2 kilometers), spotting at least 40 species that might be unknown to science, according to the U.S. National Oceanic and Atmospheric Administration (NOAA).
Scientists have known of the symbiotic relationship that exists between some hermit crab and some anemone, including the pink-spotted anemone. The Anemone protects the crab, they share food and in some cases, the anemone secretes a shell like substance which makes allows for the shell to “grow” with the hermit crab. This pairing may be a similar arrangement.
