Fish biologically swim and not walk on the ocean floor. Meanwhile, some fish species were seen on camera walking instead of swimming.

Sea Robin or Triglidae is one of those fish species that can walk across the ocean floor. Live Science reported this bottom-feeding fish have bony plates along their bodies with branched whiskers in from of their mouths. Most notable is its thickened stiff fin rays that make the sea robin walk on the ocean floor.

A video footage gathered by the scientists of the National Oceanic and Atmospheric Administration showed how sea robin can walk on the bottom. The researchers explained that walking is the actual way that sea robins do to move its body from one place to another.

Furthermore, a large-mouthed fish known as the pink frogmouth or Chaunax Pictus was also spotted walking on the ocean's ground. The pink frogmouth uses its fins to walk across the shell wall.

It was the NOAA's Okeanos Explorer that discovered the ability of the pink frogmouth to walk on the ocean floor. Meanwhile, according to Mail Online, another fish was also tired of swimming known as the angler fish.

Angler fish looks like a four-legged fish with an odd and sad face. Its fins serve as its legs which it uses to balance on the seabed. However, slightly different from the previously mentioned species of fish, this one rest on the ocean floor to wait for its prey.

Scientists believe that it was not only the sea robin, pink frogmouth and angler fish are the species of fish which can walk on the surface of the ocean. Okeanos Explorer scientists once mentioned that there are only very little known about deep-sea habitats and the communities and species on it. But, they are willing to take the risk and use possible resources to discover more species and get lots of data and information thru their expedition.
