FISH SCALING A SEVEN-FOOT WALL 
Pectoral and pelvic fins have been compared to legs and arms. A species of Catfish in India are here 
shown climbing from the Jumna Canal up to the Jumna River using their pectoral and pelvic fins. It is 
said these Catfish are provided with a special sucking apparatus which enables them to cling to the wall. 
The Jumna is the chief tributary of the Upper Ganges. It supplies the waters for the irrigation works of 
the East and West Jumna Canals.
