Mopalia
Mopalia is a genus of chitons, marine mollusks with eight overlapping shell plates. They are commonly known as mossy chitons or tree chitons, reflecting their distinctive appearance and their ability to cling to rocks and algae. These small, oval-shaped animals are found in the intertidal zone and subtidal regions of the northeastern Pacific Ocean, from Alaska to Baja California.
Characteristics
Mopalia species are characterized by their distinctive, densely covered shells. Their shells are often covered in a layer of fine, hair-like structures called spicules, giving them a velvety or mossy appearance. These spicules, along with the chiton's ability to tightly adhere to surfaces, provide them with effective camouflage and protection from predators. Their foot, which is the ventral surface of the animal, is also used for locomotion and clinging to surfaces.
Environments
Mopalia chitons are typically found in rocky intertidal zones and subtidal habitats. They prefer areas with abundant algae, which they graze on. Their ability to cling to surfaces allows them to withstand the harsh conditions of the intertidal zone, including wave action and desiccation.
