How would the amount of gravity on Pluto affect life there?

Pluto's mass is only about 1/455th of Earth's and its gravity would be 1/15th. Earth-type plants could grow immensely tall. Insects and animals could run faster and jump farther. However, the incredibly frigid temperature on Pluto (only 30 to 50°C above absolute zero) makes native lifeforms unlikely, unless very different from terrestrial forms.
