Hamineobulla kawamurai
Habe, 1950
Maximum size: 6 mm.
Identification:
This
species
has a straw colored shell with fine, wavy spiral striae.
It is marked with spiral rows of irregular white patches. When very
young, the shell is decorated with widely spaced spiral brown lines but
in mature animals the lines are replaced with irregular axial
streaks. The animal is translucent-gray with irregular brown patches
and scattered white flecks.
Natural history:
Hamineobulla kawamurai
is a moderately common species found in rocky habitats at depths
of 2-9 m (6-30 ft). It occurs at moderately exposed to highly
exposed sites but is most common at the latter (where it may be the
most numerous haminoeid in short algal turf exposed to high surge). It
lays a spherical, white egg mass anchored in algal turf. The eggs hatch
in about three days in the laboratory.
Distribution:
Maui, Kauai and Midway: widely distributed in the western & central
Pacific.
Taxonomic notes: This species is illustrated in Severns, 2011 as #8, plate 190 (misidentified in the caption as Limulatys muscarius--caption
switched with #10, plate 190). Recent DNA work supports placing it in
the Scaphandridae (Oskars, et. al., 2019). Older sources often place it in the
Bullidae or Haminoeidae.
