List of extraterrestrial life in Alien Planet

This is a list of all extraterrestrial life from the Discovery Channel show "Alien Planet"

A

Amoebic Sea

The Arrowtongue uses a sonar system to terrify prey. It has bioluminescent patches on its back it uses to scare off intruders. It has tentacle-like arms and a pair of large, two-toed, muscular legs. The Arrowtongue is called this due to a retractable appendage on its mouth that can attack prey, piercing the victim and injecting digestive juices into it. The insides of the prey are then turned to liquid, which it uses its convert|8|m|foot|sp=us|adj=on|abbr=on long appendage to suck out as food.

The Arrowtongue was the first fully-formed alien to be sighted by Leo and Ike, and performed a threat posture at the probes. Due to Leo's programming, the Arrowtongue nearly caused Leo to go offline, twice, once with its tail, and the other with its tongue.

B

Beachquill

Bladderhorns are aggressive creatures which live a solitary life in the mountain regions of Darwin IV. If a male Bladderhorn encounters another, they will duel with each other by ramming heads and showing off their bioluminescent patches.

Leo was first to encounter Bladderhorns; he discovered two rutting. The sounds created by the Bladderhorns are produced by putting air in bladders, then releasing it.

D

Daggerwrist

Sea Striders are the largest creatures ever, both on Darwin IV and Earth. They walk over the Amoebic Sea on which they feed by taking parts of it with them on their sucker-like feet. The Striders have tentacles hanging from their face and large glowing holes in their head. The nymph-like young orbit the adult Striders and are attracted to these holes. The young are also food for the sea, which extend tentacle-like columns to catch them.

When Ike is clinging on to a rock in a storm, he first sees the Striders and their young. After the storm has passed, he tags along with them, as they are heading in the same direction that Ike is going to find Leo. He studies them on the way there.

Eosapien

Grovebacks are gigantic aliens five stories high. They are two-legged but have a rudder-like leg they use for balance that is dragged along behind them. They have a semi-circle shaped head and two enormous nostrils. The Grovebacks bury themselves for long periods of time to feed on the nutrients in the soil. They have saplings growing on their back, which inject sugars into the creature. The Groveback gives the trees water in return.

Ike saw the Grovebacks twice. During the first time, he was studying the young saplings on its back, unaware that they were part of a creature. During the second time, it was attacked by a field of beach quills and died.

Gyrosprinter

JetDarters are small green flying creatures. They feed on the dead remains of any creatures killed by another predator, such as a skewer, that has not been finished.

Jetdarters only appear briefly - first feeding on the dead remains of a Skewer's kill, and then flying through a field of electric mushrooms.

L

Littoralope

Prongheads are pack hunters with a similar lifestyle to that of a "Velociraptor" or a Wolf. It stalks its prey from all directions and tries to surround it, working as a team. They kill their prey using prongs on their faces, which let out a feeding tube that inject digestive juices.

The Prongheads only starred briefly in the show, attempting and failing to kill a Gyrosprinter.

kewer

Trunk Suckers are relatively small, delicate creatures that are capable of gliding long distances. They feed on the tree sap from the Plaque-bark Tree, which is brought to the surface of the tree by Daggerwrists. Trunk Suckers use sharp claws to attach themselves to trees while feeding. They fly in small groups, rather like birds on Earth. They are also prey for the Daggerwrist.

The Trunksuckers were seen twice by Ike, the first time they were feeding on tree sap, and the second time their flock was attacked by a Daggerwrist.

U

Unth

Unths are buffalo-like aliens with two large tusks facing forward on their faces. They are heavy yet lightly built, able to run long distances but still be a formidable herbivore. They are bipedal, and rather than create sound through lungs they have secondary air sacks on their flanks, which create a recognizable 'unth' sound. The unths live on a large plain, which was explored by Leo first, before he was destroyed, and then Ike, who was searching for Leo.
