Eoperipatus totoro is a species of velvet worm of the family Peripatidae discovered in Vietnam in 2007. As of 2013, it is the only velvet worm known from Vietnam. The specific name is derived from caterpillar-like Catbus from the Japanese animated film My Neighbor Totoro. It has a distinct feature from other worms in having uniquely shaped hairs on its body surface. Its ability to spit out nets of sticky glue from its appendages is used for catching prey. Like other velvet worms in this genus, this species exhibits lecithotrophic ovoviviparity; that is, mothers in this genus retain yolky eggs in their uteri.

Catbus is a fictional supporting character in the Studio Ghibli film My Neighbor Totoro, directed by Hayao Miyazaki. It is a large, grinning, twelve-legged cat with a large bushy tail and a hollow body that serves as a bus, with windows and seats covered with fur. The character's popularity has led to a spinoff short film, toys for children, an art car, and an exhibit in the Ghibli Museum. Catbus is believed to be based on the Japanese bakeneko, an ancient urban legend where cats that grow old learn to shapeshift. In the original Japanese version of My Neighbor Totoro, Catbus is voiced by Naoki Tatsuta, whilst in the Disney English release, Catbus is voiced by Frank Welker, and by voice actor Carl Macek in the Streamline Pictures release.
