Where
seen? Small ones are sometimes seen on our undisturbed
reefs, under rocks and rubble.
Features: 4-7cm long, the shell resembles
a limpet, flat semi-spherical oval, resembles an ear especially from
the underside. There are 5-10 small holes on the upper edge of the
shell. The animal has a large fleshy foot edged with fine tentacles,
and lacks an operculum. It has large eyes on short stalks, and a pair
of long tentacles. The inside of the shell is shiny and pearly, the
outside is often well camouflaged with encrustations.
Sometimes confused with limpets. |

Human uses: Temperate climate
species grow much larger than tropical species, and are harvested
for their shell, used for shell crafts, and the animal is eaten as
a delicacy in Asia. Due to the high value of the animal in the food
trade, even smaller tropical species are threatened with over collection.
Status and threats: Some of our
Abalone species are listed as 'Endangered' on the Red List of threatened
animals of Singapore. Due to the loss of natural rocky shores with crevices where
they thrive. Seawalls do not appear to be a viable alternative habitat for this animal. |
