Biology
Boekind were large, humanoid heads with numerous tendrils which terminated in round pod-like structures in place of hair. (DW: The End of the World)

Boekind can communicate telepathically and are able to speak, though they often prefer telepathy. (DW: The End of the World, New Earth, Gridlock)

Life cycle
Little is known about Boekind reproduction, but it is known that they could become pregnant and give birth. The actual minimum and maximum of young per pregnancy is unknown, but the Face of Boe gave birth to six children. (DW: The Long Game)

Technology
The only technology known to be used by Boekind was a life support tank with added teleport in which the Face of Boe lived permanently, however even this may have not been created by Boekind and may be a creation of another race. (DW: The End of the World, New Earth, Gridlock)

History
In the year 200,000, the Face gave birth to six children, the Boemina, although in 40 years time even the Boemina would die (DW: The Long Game). The Face later nearly died in the year 5,000,000,023 but managed to survive (DW: New Earth), and later sacrificed himself to save the inhabitants of New New York in the year 5,000,000,053.
