Shansheeth

The Shansheeth were a species known as galactic undertakers. They travelled through space to return lost heroes to their kin.

Biology
They had a likeness to Earth vultures. They had hunched shoulders with their necks protruding from the middle section of their body. They were able to project an energy beam from their hands offensively. (SJA: Death of the Doctor)

History
In 2010 a rogue group of Shansheeth, the Claw Shansheeth of the 15th Funeral Fleet pretended to return the corpse of the Doctor to Earth, proclaiming him dead. They planned to drain energy from Sarah Jane Smith and Josephine Grant through their memories of the Doctor to gain access to his TARDIS and prevent death. They were killed when their Memory Weave overloaded and self destructed. The Wide Wing of the High Shansheeth Nest apologized on behalf of the rogue group. (SJA: Death of the Doctor)

Clyde Langer later used the Shansheeth as inspiration for his drawings. (SJA: The Empty Planet)
