Dave the giant earthworm has set a new world record. Dave is about as long as a standard bowling pin is tall and weighs as a small chocolate bar.

The giant earthworm was found in the U.K. and is not only the longest ever found in Great Britain but also the heaviest known wild worm in the world. The worm measures nearly 16 inches and weighs almost an ounce, double the weight of the previous record holder found in Scotland at 0.5 ounces.

Dave’s size is particularly impressive for a worm in the wild, according to experts. With plenty of natural predators and other threats, the Natural History Museum noted that earthworms don’t typically survive long enough in the wild to reach such a record size.
