Corbanite

Corbanites are a sapient, amphibious race hailing from an unknown planet.

Description
Corbanites are known for requiring very specific conditions in their surroundings to survive. Below a certain temperature and humidity, the typical Corbanite body suffers much the same kinds of issues that a frog does when exposed to excessive cold and dry air.

In a way, this makes them similar to the Irumok, as both races require environmental suits to live off of their homeworlds - however, due to slight differences in the nature of their living requirements, Corbanites have learned to build small, sustained habitats where they don't need their suits.

Physically, Corbanites are slightly weaker and less agile than the average human - however, they are remarkably intelligent and inventive, capable of quickly figuring out how nearly any kind of machine works in a matter of minutes to hours. Avid merchants and mechanics, Corbanites are very engaged in interstellar commerce. They are also close allies of mankind, and get along very well living with humans.

Known Corbanites
One Corbanite named Gurruno, old friend of "Hot Ice" Hilda, owns the space station Blue Heaven.
