Hundreds of small fish move along the muddy banks when the tide recedes at Reju Khal in Cox’s Bazar. Locally known as ‘Bender’ or ‘Dakur fish’, these fish are a familiar sight for local residents.
The fish are known for their unusual movement. They remain in the water during high tide but move onto the muddy banks as the tide goes out.
During low tide, the fish can be seen moving in groups through the shallow waters and across the muddy banks of Rezu Khal. Unlike most other fish, they use their pectoral fins to move on wet mud outside the water.
Amin, a resident of the Reju Khal area, said the fish become particularly visible along the banks when the tide recedes.
“We have been seeing these fish since our childhood. They are commonly known here as Bender fish,” he said.
Local fisherman Hasan said the fish are abundant in Reju Khal, although local people generally do not catch them for consumption.
“They can be seen in large numbers in the shallow water and near the banks during low tide,” he said.
The fish generally inhabit areas influenced by tidal movements. During high tide, they remain underwater, while during low tide they move onto exposed banks, muddy surfaces and small pools left behind by the receding water.
You may also see them near other fish, marine algae, and small pools that form with the tide’s ebb and flow.
Although locally known as ‘Bender’ or ‘Dakur fish’, a fisheries expert must confirm the exact scientific and commonly accepted species name.
Local residents are familiar with these fish moving along the banks at low tide, but it could offer tourists and visitors a new experience.
Their movement with the tide’s ebb and flow also offers an intriguing glimpse into Rezu Khal’s aquatic biodiversity.
