A limpet
Yes.
The limpet has only one shell, making it a univalve. Molluscs with two shells, such as clams and mussels, are bivalves.
A limpet has a shell that is much stronger that a snail's and they are small and not really a good food source
Limpets have gills to protect themselvesAdditional answerGills are not a protection any more than human's lungs are a protection.. They are a means of breathing. The protection is the hard conical shell and the way the limpet firmly attaches itself to rocks.
The limpet hides in its protective shell and sucks hard onto the rock or surface that it is on making it almost impossible to remove with ease. However the limpet is defenseless against birde with strong beaks eg the african black oyster catcher, even though it doesn't actually eat oysters. Written by MAC from BHS
They have a hard shell on the outside of their body which is the exoskeleton. It eats only at night as it is the safest time to be about. I hope I was of help, Essondon xox
By going to places where the enemy does not go. For instance, if a bird is attacking the Limpet it will go into the nearest body of water where the bird will not follow to. Limpets don't really need to move because their shell can protect them. They either flee or clamp themselves incredibly hard to the surface they're attached to. Scientists have done a study on certain subspecies and discovered that the limpet can identify its attacker chemically. (Wikipedia is a good source)
The shell is hard.
Barnacles don't move once they settle down as a tiny larvae on their chosen surface. Limpets can move around on their broad foot. Some limpets have holes at the top of the hard shell, others do not. The hole is not closed by plates.
Yes, a limpet is a type of mollusc. Specifically, it belongs to the class Gastropoda, which includes snails and slugs. Limpets are characterized by their conical shell and strong muscular foot that allows them to cling to rocks along the shore.
Grasshoppers do not have a hard shell.
