Jumper is a male spider from Xanth. His talent is making silk. He was first introduced in Castle Roogna as a major character.
Jumper is an ancestor of Jumper.
Jumper is the jumping spider who accompanied Dor in his tapestry adventure. Since Dor is tiny at these times, Jumper seems monstrous. By means of his silk, Jumper can suspend himself and even fly.

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.
