  • 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 glaucothoŽal 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)
