Morboians are green alien creatures. Very little is known about the species; we know not of the name (Morboians coming from Morbo) or their home planet, and the only known creatures are Morbo and Fawn. We know from what Morbo has said however that there is a large Morboian society.
The Native Martians are the original inhabitants of Mars. They sold their land to the Wong family for a giant diamond, which they thought was worthless, as they had no concept of ownership. They left Mars, bought a planet with the diamond, and abandoned the Martian caves.
Neptunians are a humanoid species from Neptune which shares many characteristics of humans. There are a few differences though: Neptunians have pig-like noses, purple skin and four arms, and their hair is almost always black, dark blue/green or brown.
The Neutrals are humanoids of average height and build. They are hairless, their skin is a dull grey, and their faces are not capable of displaying emotions. In fact, it's not entirely clear if they have emotions at all. They have a very detached outlook on life.
Nibblonians stand about one foot tall, hairless, and have two large eyes as well as a third eye on an antenna in the center of their foreheads. They are black in color, with pale yellow circles on their bellies and around their mouths. They are widely considered to be the cutest race ever to exist, though this is something the Nibblonians resent, even though they exploit it.
The Omicronians are a violent, aggressive race from Omicron Persei 8. Omicronians stand around eight feet tall, and have characteristics of reptiles. Their skin can have various colours, ranging from a greenish-yellow to dark brown, their eyes are yellow with oval pupils.

The Trisolians are a species whose bodies are made from liquid-matter. At night they glow as part of their nocturnal phase.
The Venusians are mentioned in many forms. The painting Venus de Venus shows a female blob, so Blobs may actually be Venusians.
The Vincians come from Planet Vinci, and resemble humans, but apparently live to be a very old age. They are also extremely intelligent as a standard, though this may be cultural and not biological.
