Nagaraja is a Sanskrit word from naga (snake) and raja (king) meaning "king of snakes". It is applied to three main deities, (Sheshanaga), Takshaka, and Vasuki. Ananda, Vasuki and Takshaka are brothers, children of Kashyapa and Kadru, who are the parents of all snakes.
Shesha, Vasuki, and Takshaka 
Shesha, the eldest brother, was a devotee of Vishnu, and represents the friendly aspect of snakes, as they save food from rodents. Lord Vishnu is always on continuous meditation (Yoganidra) with Ananda forming a bed for him, and this posture is called Ananda-Sayana.
Vasuki, the younger one was a devotee of Lord Shiva. Lord Shiva always wears Vasuki around his neck.
Takshaka represents the dangerous aspect of snakes, as they are feared by all due to their venom.
At Nagercoil in Kanniyakumari district of Tamil Nadu, a temple dedicated to Nagaraja exists.
There is another famous temple named Mannarasala in Alleppey district of Kerala. The deity in this temple embodies both Anantha and Vasuki into one.
