Clam Helix
Evolved from F. filtaclama. Their tentacles also evolved very small spines in mutations in order to filter feed(same way they evolved their other claws). Their shells changed to be more rock like for camouflage in order to avoid potential predators like S. pygmeus.
Found in zone 5 they are found diversely in deeper waters to the shallows as long there is food to be found. They feed on small pieces of S. podius, detritus, biofilm, F.foliumegaeus and F.foliumicroeus. Their arms or tentacles are use catch food which they would put it in its mouth to feed on it. They usually burrow themselves living their tentacles and body exposed but can easily retract them to the shell and burry deeper to avoid attention from bigger species(such as S. pygmeus). They can also burry themselves in substrate feed on the detritus or biofilm in the substrate. They can be found in groups just huddled together filter feeding but also can be found alone filter feeding (they do not mind company) They are found in more denser groups in shore lines as more food are washed ashore. They are still found in deep parts feeding on the water column and on the ground still found in groups. Their spine filaments on their tentacles help them catch more food due their filaments trapping more food for them.Despite keeping their shell buried most of the time, the camouflage helps them when they're exposed by currents and helps seeking a new location without being notice.
They breed asexually and they lay and carry their eggs in their shells. When the eggs hatch the babies come out of their parent shell and they feed on detritus and biofilm under the substrate until their big enough to be on the surface. They get up to 5-10cm
