A species of sea robin called Prionotus carolinus studied by researchers used their leglike appendages for walking, digging and sensing the seafloor. – Anik Grearson
Harvard and Stanford researchers were understandably amazed the first time they encountered a walking fish called a sea robin.
The unusual animal has a fish’s body, delicate fins that resemble a bird’s wings and six leglike appendages similar to those of a crab.
When the scientists decided to study the sea robins on a genetic level, they encountered a surprise in the lab: While some sea robins use their “legs” just to walk, others use them to dig for prey on the seafloor.
The team captured video of the digging sea robins, whose specialized appendages are covered in sensitive taste buds akin to those on a human tongue to detect prey.
