The Death Song is a Mystery Class dragon from Dragons: Race to the Edge.
The Death Song uses a siren-like song to lure it's prey. The secret behind this amazing feat is the Death Song's extra cervical vertebrate. When the Death Song calls, its extra vertebrae expand into its frills, and its song is able to be projected to specific targets up to a mile away.
After striking its prey, the Death Song covers it in a yellow, liquid substance which traps and preserves victims as it hardens into a stiff amber cocoon. This cocoon is so strong, it is only penetrable by flame. Afterwards, the Death Song returns to finish it's prey off. It does this by breaking the prey out of the amber and then eating them. As they can consume medium size dragons like Gronckles in few minutes
