The first and second walking legs carry pincers at their proximal ends; hence they are known as the chelate legs. The last three legs are non-chelate. The second walking leg is very much larger and bears spines and setae. 

It is, therefore, known as the large chela, whereas the first walking leg is known as the small chela. The walking legs help the prawn to crawl upon the river bed. The chelate legs are organs for offence and defence and help in holding the food before being taken. Gonopores are situated at the bases of the third walking legs in female; but in male, they lie at the bases of the fifth walking legs.
