Esthetes

Definition

Esthetes are specialized sensory structures found in the mantle of chitons, a type of mollusc. They function in light detection and possibly other sensory roles.

5 Must Know Facts For Your Next Test

1. Esthetes are embedded within the dorsal shell plates of chitons.
2. They contain photoreceptor cells that can detect changes in light intensity.
3. Esthetes may help chitons respond to environmental changes by detecting predators or shading.
4. In addition to photoreceptors, esthetes might include other sensory cells for chemical and mechanical stimuli.
5. The presence and complexity of esthetes vary among different chiton species.
