For most land-based creatures, a lack of limbs would lead to mobility problems. Living in water, however, fish can move with freedom and agility despite their lack of limbs. Instead of arms and legs, fish use their fins. In this riddle, the term gshog ba is used in reference to fins. This word can be used for fins but is more commonly used to identify wings. This word choice, along with the illustration of a breastbone connecting two wings would draw the riddle-solver's attention to animals in the avian family. Instead, the answer to the riddle is a fish.
