Paguritta is a genus of hermit crabs in the family Paguridae, known as coral hermit crabs.[2] Atypically for hermit crabs, this genus comprises species which live within polychaete tubes associated with corals (such as those of Spirobranchus giganteus),[3] or bore their own holes in living coral,[4] depending on species. They feed by filtering using their modified antennae equipped with setae and setules.[5][6][7]

There are seven species assigned to this genus:[1][8]

  • Paguritta corallicola Lewinsohn, 1978
  • Paguritta gracilipes Melin, 1939
  • Paguritta harmsi (Gordon, 1935)
  • Paguritta kroppi McLaughlin & Lemaitre, 1993
  • Paguritta morgani McLaughlin & Lemaitre, 1993
  • Paguritta scottae McLaughlin & Lemaitre, 1993
  • Paguritta vittata Komai & Nishi, 1996

A diagnostic feature of this genus is the complete absence of pleopods in the males and their reduction in females; the former trait is shared with multiple other genera,[6] but only the females of Anapagurus drachi experience a similar degree of pleopod reduction.[9] Another is the symmetry of their uropods, thought to be due to their niche; hermit crabs inhabiting gastropod shells have asymmetrical uropods due to the shell's spiral. Paguritta kroppi individuals may have both male and female gonopores.[6]
