Dardanus calidus
Is a species of hermit crab and can grow to a length of 12 centimetres (4.7 in). It uses large gastropod shells, such as those of Tonna galea and Charonia species, which it often decorates with one or more sea anemones of the species Calliactis parasitica. The relationship with the anemone is truly symbiotic, since the anemone gains scraps of food from the hermit crab, while the crab benefits from the anemone's stinging tentacles deterring predators. Dardanus calidus is a scavenger, feeding on decaying matter from the sea bed. It has been collected from depths greater than 100 metres (330 ft), but is more typically found in shallower water.

Scyllarides latus
The Mediterranean slipper lobster, is a species of slipper lobster found in the Mediterranean Sea and in the eastern Atlantic Ocean. It is edible and highly regarded as food, but is now rare over much of its range due to overfishing. Adults may grow to 1 foot (30 cm) long, are camouflaged, and have no claws. They are nocturnal, emerging from caves and other shelters during the night to feed on molluscs. As well as being eaten by humans, S. latus is also preyed upon by a variety of bony fish. Its closest relative is S. herklotsii, which occurs off the Atlantic coast of West Africa; other species of Scyllarides occur in the western Atlantic Ocean and the Indo-Pacific. The larvae and young animals are largely unknown.
