WebApr 12, 2024 · We recently discovered a family of octopus-specific chemotactile receptors (CRs) that are used by octopus arms to detect poorly-soluble natural products, thereby defining a form of contact-dependent, aquatic chemosensation (van Giesen et al, Cell, 2024). CRs form ion channel complexes to mediate diverse signal detection and filtering.
