Animal Care/Snail shells with D shaped openings

Hermit crabs that usually prefer shells with "D" shaped openings:

  • Equadorian/Pacific hermit crabs or "Es" (coenobita compressus)
  • Cavipe hermit crabs or "Cavs" (coenobita )

As pets they tend to give preference to particular snail (class Gastropoda, phylum Mollusca) shells (Picture2  links may contain pictures of shells that have been misidentified; not all shells at the "common names" links may be appropriate for hermit crabs):
