Silithid queen

From WoWWiki

The Silithid queen is a gigantic Silithid creature in the Hatchery of Ahn'Qiraj, always laying eggs.

Like all silithids the queen exists to serve the hive, and is specialized in her role by laying eggs.^{MG 121}

While silithid haven’t been a visible part of the world long enough for anyone to accurately gauge their lifespans, some researchers think that after achieving adulthood, a common silithid can live for up to 5 years, although queens can survive for decades.^{MG 121}
