There is no reason why the jumping spider shouldn't have made the top ten vote....there should be no down vote button because people abuse that just like they would if you could vote for the same one multiple times. People were down voting the idea based on their own opinions of how it would "break" the game. First, these are suggestions to the Devs who would modify the creature to keep it from "breaking" the game. We need more dinosaur option for knocking out wild dinos which are more mid and late game playable. Please look into this issue and remove the down vote button for the next submission thanks.
