Petalifera lafonti (Fischer, 1870)

Maximum size:
30 mm (Bertsch
& Johnson, 1981).
Identification:
This
sea
hare is translucent-cream with longitudinal
powder-white
stripes. Its body is smooth and flattened when
resting on its host
algae.
Natural history:
Petalifera lafonti
lives on the brown algae Padina
on which it's superbly camouflaged. It appears to be
rare in rocky
habitats. We've never seen it on Maui but Scott
Johnson found
one animal at an exposed site on Oahu. Shells found
in sand
samples from Halimeda
kanaloana
beds suggest that it may be more common in that
community at greater
depths.
Distribution:
Maui,
Oahu and French Frigate Shoals: circumtropical.
Taxonomic notes:
This
is
the species listed in Kay, 1979 and Bertsch and
Johnson, 1981
as Petalifera
petalifera
(Rang, 1928).
