Barnacles glue themselves for life with super cement
Barnacles create a lifelong bond to surfaces using an extraordinarily strong, natural cement, inspiring scientists to develop new eco-friendly adhesives for various applications.

These glands secrete a powerful, cement-like adhesive that hardens upon contact with seawater, allowing barnacles to withstand powerful waves and currents for their entire adult lives. This amazing adaptation helps them avoid predators and filter-feed effectively.
