Remora suckerfish use an adhesive disk on their heads to attach to marine animals. This disk is an evolutionary adaptation featuring a bony backbone and specialized plates with tiny spikes. The adhesion process involves pressing against the host’s skin to create a low-pressure zone while the spinules interlock with the surface. This mechanism functions like a suction cup combined with Velcro. The adaptability of remora disks allows them to adhere to a variety of hosts, providing significant evolutionary advantages for the fish.
Remora adhesive disks are an evolutionary adaptation of the fish's first dorsal fin, supported by a bony structure that allows secure adhesion to fast-moving hosts.
The disk uses a combination of low-pressure zones and backward-facing spinules to create a bond similar to suction cups and Velcro.
Scientists have reverse-engineered these disks to create adhesives capable of working in wet environments, inspired by nature's evolutionary solutions.
The flexibility of remora disks allows different species to adhere to a variety of hosts, showcasing a unique evolutionary advantage.
