Rosy Hermit Crab

Calcinus rosaceus

The Rosy Hermit Crab is a member of the crustacean family Diogenidae, commonly found in the Western Indian Ocean, specifically around Oman. This species is benthic, meaning it lives on the ocean floor, and is typically found in tropical waters. This behavior makes them easily distinguishable from other crustaceans. The Rosy Hermit Crab's ecological role includes scavenging, which involves feeding on detritus and organic matter found on the ocean floor. This diet helps maintain the health of the marine ecosystem by recycling nutrients. Divers encountering the Rosy Hermit Crab may find it on various substrates, where it uses its shell as a mobile home. While its conservation status has not been evaluated by the IUCN, it is recorded at numerous dive sites.
