Purport: 

Materialistic demons sometimes appear to be very powerful and are seen to establish their supremacy throughout the world. Here also it appears that Hiraṇyākṣa, by his demoniac strength, actually established his supremacy throughout the universe, and the demigods were afraid of his uncommon power. Not only were the demigods in space afraid of the demons Hiraṇyakaśipu and Hiraṇyākṣa, but so also were the aquatic animals within the sea.
