Tash's species

Tash's species are an unnamed species of amphibianoid humanoids presumably native to the Delta Quadrant.

Biology
They have pale skin with multiple black spots and a flat crest extending from their noses to the top of their heads. They also appear to have sucker-like structures on their thumbs.

Notable members
A member of this species named Tash is a scientist who somehow ended up hundreds of light-years away from his home planet. Using advanced technology he created a graviton-based catapult to send his starship home much faster than warp drive could. With the help of the USS Voyager crew, he managed to complete the mechanism and use it in a successful trip. The Voyager also benefited from the catapult, being able to use it to cut three years off of their long journey back to the Alpha Quadrant.
