Tata is a male dogfish from Xanth. He was first introduced in Ghost Writer in the Sky as a major character.
Tata is a character in "The Lizard of Waz" written by Goar. He is a computer dogfish pet. He was able to leave and became the host to Princess Eve. His bark is worse that his byte. He was a witness at the wedding of Rhythm and Cyrus. He now serves aboard Fibot and is translated by Peeve.

Human men and women will not have a species in their entries. Also, if the surname of the character is the character's species, it was dropped.
If the character is a child, it will be in the description. The child will more than likely be an adult by this time in the Xanth series.
Many species are single gender, so their entries will not mention it. The species are Fury, Muse, basilisk, cenmaid, cenmare, cockatrice, dryad, maenad, sand witch, sandman, and woodwife. Harpies and nymphs are usually female, and fauns are usually male; but there have been a few exceptions that are noted.
In some instances, I have made educated guesses on gender, species, and some birth years.
