This File Shell (Lima lima) was uncovered when we were looking for worms under some rocks at Tanjung Rimau. Its appearance took us by surprise. We were both fascinated by the bright red tentacles and its shell valves clapping locomotion.
File Shells use an adductor muscle to clap their valves in order to achieve their free-swimming ability. The red tentacles are sticky and as a mean of defence, they’ll break off when attached to predators. This will thus allow the shells to make a quick getaway.
Our intertidal shores are full of captivating fauna from a myriad of forms and colours. The species diversity is mind-boggling.
Do go out there and explore all the nooks and crannies!!
