Facts
- Growth might be limited by the availability of shells for housing (Ref: Lanc1988)
- Two conspicuously different larval forms: zoeal form (swimming thoracic appendages) with typically has four stages, and glaucothocal form (corresponding to brachyuran megalopa, swimming with abdominal appendages) with a single stage (Ref: Lanc1988)
- The polychaete Nereis fucata may live in the same shell stealing food (Ref: Waza)
- The hydroid Hydractinia echinata is frequnetly found on shells ocupied by hermit crabs (Ref: anemoon)
