Why in the news?

Sea robins are ocean fish particularly suited to their bottom-dwelling lifestyle, six leg-like appendages make them so adept at scurrying, digging, and finding prey that other fish tend to hang out with them and pilfer their spoils.
Sea robin “legs” are extensions of their pectoral fins, of which they have three on each side. The “legs” are occasionally used for scratching at the sand surface to find buried prey, without visual cues.
A different species of sea robin use their legs for locomotion and probing, but not for digging.
