User blog comment:Lightning the Skrill/Deathsong, Slithersong?/@comment-26219548-20150731125654

In Rise of Berk, Deathsong appears to be a subspecies of the Slithersong. The Deathsong appears to be a particular breed of Slithersongs that they met. I think that we should have another page, just like the Whispering Death and Screaming Death. And their appearance is quite different.
