Sea Anemone & Hermit Card Moving House Video
Some sea anemones and hermit crabs establish a lifetime symbiotic relationship where both animals gain an advantage. This particular type of symbiotic relations is referred to as commensalism. This means that each animal is getting a benefit from the other and neither is negatively impacted by the relationship. The sea anemone attached to the hermit crab’s shell acts as the crabs body guard. In times of danger even entirely covering the crab with its tentacles and stinging threads. Most predators wouldn't dare attack this line of defence. The crab in turn provides the sea anemone with scraps from its leftover meals and also provides the anemone mobility by moving it from place to place. By riding on the hermit crab’s back the sea anemone has a better chance of catching plankton and other creatures that may pass by its tentacles.
This relationship can be so strong that sometimes young hermit crabs will seek out a young sea anemone an intentionally attach it to its shell where they may become partners for life. As the hermit crab sheds its shell it will move the sea anemone along to its new shell.
