‘Crazy little fish have a lot to tell us’: sea robins use ‘legs’ to taste way to prey

Fish monitor sea floor using leg-like structures covered in bumps similar to those on a human tongue, study finds

A bizarre type of fish with leg-like appendages uses its limbs not only to scurry around but also for tasting" the sea floor to find buried prey, researchers have found.

Sea robins have six leg-like structures that are formed from modified fins and are known to use them to walk across the sea floor and even flip over shells in a hunt for prey.
