About Limpets. The limpet is a mollusk and it is a member of Acmaeidae family. The limpets can be found throughout littoral zones and they are usually found on rocks near seas or oceans. The limpets have a flat shell and they stick on the rocks by using a muscular foot which allows them to remain attached on rocks if a big wave comes.
The limpets we sell are the herbivorous Black Ribbed Limpets, (Lottia leucopleura).They eat algae and diatoms-they are 100% reef safe.Limpets are similar to snails, except they have a round shell that caps the top of their body, they cling closely to rock to cover their bottom half, (as compared to the more evolved snail that can retract into its shell).owever, limpets are unable to right themselves if they are turned upside down unless there is a strong current for them to utilize.When adding limpets to your tank, place them on the rocks so they can establish a grip. During this time, before they can seal themselves down, they may be vulnerable to predation.
