The Lateral-striped Limpet has a south-east Australian distribution. Its range includes southern Qld, NSW, Vic, and Tas to eastern SA. (QLD, NSW, VIC, TAS, SA)Features:
The Lateral-striped Limpet has a small, star-patterned, cone-shaped limpet shell. It is a long oval in outline, with some are narrower at the rear. The shell grows to a length of 12-20mm a width of 17 mm and a height of 8-9 mm. The shell sculpture consists of 12-15 irregular, rounded ribs that are often pitted and worn. Some ribs are bolder than others are and form a star-like pattern. Some specimens may lower (depressed) and may be heavily eroded. The shell apex is at the hind third. In NSW, the form P. l. submarmorata, Phrilsby, has finer, narrower ribs instead of the heavier prominent ribs of the southern form.
The animal has a pale transparent mantle, while its body is translucent. You can see the shell faintly through the body and the veins can be seen quite clearly. The foot edge is yellow. The top of the head is lemon yellow, with fine, long, translucent tentacles. The gill plume is small and also translucent.
The shell colour is dark brown, greyish if eroded, with broad light-coloured rays down most of the ribs. The shell interior is bluish-white with a dark brown margin. The spatula is brown, spotted with blue or brown and is bordered with white at the end of the ribs.Ecology/Way of Life:
The Lateral-striped Limpet lives at mid- to high-tide levels on exposed rocks, or in holes and crevices, on medium- to high-energy coasts. It tends to prefer flat rock surfaces. It is often found amongst barnacles. It breeds throughout summer. It is often associated with the air-breathing, pulmonate siphon shells, Van Diemen's Siphon Shell, Siphonaria diemenensis, Corded Siphon Shell, S. funiculata and the Granuled Limpet, Notoacmea granulosa.Interaction with Humans/Threats:
The Lateral-striped Limpet is locally common on many rocky shores of south-eastern Australia, especially on southern shores. It seems to be under no threat of human interaction.Other Comments:
Patelloida latistrigata, Angas, 1865. Other names have been Collisella latistrigata, Collisellina latistrigata, Collisellina marmorata and Collisella gealei.
Patelloida comes from the Latin word patena or patina, meaning a plate. Latistrigata comes from the Latin words, lati, meaning broad, and striga, meaning a furrow or a flute of a column. This describes the fluted column shape of the ribs in this species.Further Reading:
