Chitons

Chitons are marine mollusks that play a crucial role in rocky shore ecosystems by grazing on algae and biofilm using a specialized, rasp-like radula, while their strong muscular foot helps them cling to rocks and slowly move across surfaces, often returning to a specific home scar after foraging; their unique multi-plated shells offer protection against predators, and the embedded sensory organs known as aesthetes help them detect light and navigate their environment effectively.
