The Manta Riders are an invention of Aviva's which serve as a source of transportation for the Wild Kratts crew; they are mainly used by the Kratt brothers as a faster means of underwater travel. ( as an alternative to the Amphi-Sub) They were modeled and designed after the manta ray, specifically for underwater travel. One of the more featured inventions, they are often seen destroyed and/or damaged shortly after the Kratt brothers use them (possibly as a running gag). They were introduced in Mystery of the Weird Looking Walrus.
