Mukade is the Japanese word for centipede.
"Scolopendra gigantea, also known as the Amazonian giant centipede, is the largest extant species of centipede in the world, reaching over 30 cm (12 inches) in length. It is known to eat bats, catching them in midflight, as well as rodents and spiders. The prehistoric Euphoberia was the largest known centipede, growing up to one meter (39 in) in length.
There are rumors that state that the Galápagos Islands giant centipede (Scolopendra galapagoensis) can reach sizes of up to 25 inches, although these rumours may result from the rarity of the particular centipede. Captive Galapagos centipedes don't often exceed 8 inches in body length.
The garden centipede, the most common centipede in North America, is a much smaller variety, rarely exceeding a few inches in length."
