Dardanus calidus is a species of hermit crab from the East Atlantic (Portugal to Senegal) and Mediterranean Sea.
Description
D. calidus can grow to a length of {{convert|12|cm}}. 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.{{cite book |author=Lesley Orson Wood & Lawson Wood |year=2006 |title=Malta, Comino and Gozo |series=Globetrotter dive guide |edition=2nd |publisher=New Holland Publishers |isbn=978-1-84330-942-0 |chapter=Hermit crabs |pages=76–77 |chapter-url=https://books.google.com/books?id=_gWTQNJhDccC&pg=PA77}} 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.
Distribution and ecology
Dardanus calidus is a scavenger, feeding on decaying matter from the sea bed.
It has been collected from depths greater than {{convert|100|m}}, but is more typically found in shallower water.{{cite book |editor-first1=R.

Taxonomic history
Dardanus calidus was first described by Antoine Risso in 1827, under the name Pagurus calidus, and was transferred to the genus Dardanus by Jacques Forest in 1958.{{cite web |author=Michael Türkay |year=2010 |title=Dardanus calidus |editor=P. McLaughlin |work=World Paguroidea database |publisher=World Register of Marine Species |url=http://www.marinespecies.org/aphia.php?p=taxdetails&id=107198 |accessdate=October 9, 2010}} The larval form Glaucothoë rostrata, described by Edward J. Miers in 1881, has also been assigned to D. calidus.{{cite journal |author=Anthony J. Provenzano, Jr. |year=1963 |title=The Glaucothoë stage of Dardanus venosus (H.
