Alien lifeform

Alien creature
An alien lifeform seen on a viewscreen depicting data from the Enterprise-D library computer. (TNG: "The Last Outpost", "Datalore")
Ba'ku animals
- See: Ba'ku animals
Dark matter nebula planet animal
On the coastal regions of this planet, cries of this unseen animal could be heard in the background. (DS9: "Rocks and Shoals")
Ferenginar creatures
Two statues depicting animals could be seen in Ishka's home on Ferenginar. (DS9: "Family Business")
Footprint and cell sample aliens
Footprints and corresponding cell samples of several species were stored in the library computer of the Enterprise-D. Samples of at least five alien species were compared to the footprints and cell sample of the Tarchannen III species prior to its discovery. None of the samples was similar to the Tarchannen III lifeform however. (TNG: "Identity Crisis")

Goralis III animals

A wolf-like animal from the Goralis system
While stranded on Goralis III in 2375, Worf killed a large furry mammal, somewhat similar to a wolf, for food. Worf also mentioned the planet having predators that might pose a threat to him. (DS9: "Penumbra")
Horned creature

A horned creature
The stylized image of a possibly reptilian or saurian creature with a unicorn-like horn could be seen on an Alpha Quadrant terrorist communicator and as a badge in use by two Delta Quadrant species, the Mari and the Ledosians. (TNG: "Starship Mine", VOY: "Random Thoughts", "Natural Law")
Larval space creature

A larval space creature
At some point in time, this larval spaceborne species was encountered by the USS Cerritos, and attached itself to the end of the ship's port nacelle. (Star Trek: Lower Decks opening credits)
Moon creature
A Delta Quadrant Mikhal Traveler claimed to have landed on a moon only to have discovered (after sustained moonquakes) that it was actually a creature, a living being so massive it generated its own gravitational field and so immense that it supported its own ecosystem. Another traveler, who had visited the system in 2373, expressed skepticism, as his sensors had not picked up anything like that. (VOY: "Darkling")
New Earth primate
The New Earth primate was an intelligent but non-sentient primate species native to the planet called "New Earth."
Kathryn Janeway attempted to communicate with the primate during her brief stay on the planet in 2372, claiming she sensed intelligence in it. However, Chakotay doubted it could be domesticated. (VOY: "Resolutions")
Non-corporeal species
Promenade skeleton

A fish-like skeleton
The skeleton of an animal, possibly fish-like, was displayed on Deep Space 9's promenade. (Star Trek: Deep Space Nine)
Rigel IV aliens

Aliens encountered on Rigel IV
These aliens, encountered on Rigel IV, were displayed on viewscreens depicting data from the Enterprise-D library computer. (TNG: "The Last Outpost", "Datalore")
Ruah IV species
Several animal species lived on the landmass of the planet Ruah IV as of 2369. (TNG: "The Chase")
Slug-o-Cola slug
The labels on Slug-o-Cola bottles featured an image of an apparently man-sized, slug-like tentacled creature, gorging on the cola. (DS9: "Profit and Lace")
Soukara lizard

An iguana from the planet Soukara
The Soukaran iguana was a type of lizard native to the jungles of the planet Soukara. (DS9: "Change of Heart")
Soukara mating creatures
These two creatures made mating calls to each other as Jadzia Dax and Worf traversed the jungles of Soukara in 2374. Upon hearing them howl together after calling and responding, Dax mused, "Another happy couple." (DS9: "Change of Heart")
Trophy skull
Several skulls which appeared non-humanoid were in evidence on a Hirogen trophy wall in 2374. (VOY: "Hunters")
A large skull was hanging in a net aboard a Hirogen warship in 2374. It was from a lifeform which was previously hunted down by the Hirogen. (VOY: "Prey")
The Waters marine life

A massive eel-like aquatic creature attacks the Delta Flyer at the center of The Waters
This marine lifeform was encountered under the surface of "The Waters" at a depth near 600 kilometers. The creature, which was likened to the electric eel found on Earth, was significantly larger and more powerful that the Earth counterpart, as it emitted biothermic discharges that exceeded 500,000 volts. (VOY: "Thirty Days")
