Sea robins are good swimmers but they also can use their pectoral fins to “walk” along the bottom of the ocean, looking for prey. The sensitive fins let the fish feel things they encounter and they can be used to move and manipulate small objects.

How do sea robins walk?

Sea robins have three "walking rays" on each side of their body. They are derived from the supportive structures in the pectoral fins, called fin-rays. During development, the fin-rays separate from the rest of the pectoral fin, developing into walking rays.

Can sea robin Fly?

The pectoral fins are not actually "wings" and it does not have the capability of flying, but it can use its "wings" to move through the water in quick, short, "flights." When alarmed it spreads its "wings" increasing its appearance in size as a threat to predators.
