Scientists say they’ve confirmed how remora fish grow a weird sucking disc on their heads.
Remoras, which can be up to 3 feet (1 meter) long, have a slatted disc above their eyes, which sort of looks like the bottom of a sneaker. It acts like a sucker and allows them to attach to manta rays, sharks, and boat hulls in tropical waters. But the fish aren’t parasites; rather, they harmlessly hitch rides and feed off of scraps
Zebra Crab (Zebrida adamsii)

In turn the crab is defended by the urchin’s
