Hydrophiidae

The Hydrophiidae is Snake Oiler's T-180 from the Speed Racer film. Like his rally car, this WRL racer is also part of the Hydra-Cell racing team.

Background
Those who watch the movie closely can see the Hydrophiidae in the opening race at Thunderhead. Unfortunately for Snake Oiler, the car is not seen after that since the Hydrophiidae also crashes in that race. In Speed Racer The Videogame however, the Hydrophiidae gets a bit more "screen time" as it is a playable car.

Trivia

 * "Hydrophiidae" is another word for a sea snake, a type of snake that is aquatic and inhabits tropical waters of the Pacific and Indian oceans.
 * In the files from the Videogame, this car is referred to as "Rattler".
