Venber

The Venber are a near extinct race of non-carbon-based lifeforms from a frozen moon called Venbea.

Physiology
The Venber weren't carbon-based lifeforms, and were susceptible to melting at room temperature. They were eight-feet tall, humanoids, with heads shaped like a hammerhead shark with big, dark globs on each side for eyes, and flashes of blood-red and midnight-blue running along their flanks, shoulders, and converging in their faces.

With two thick upper arms growing out of their broad shoulders. Their upper arms split at the elbows to make two forearms and they used two of their forearms, one right and one left, to propel themselves forward like ski poles on their ski-like feet. They are also able to use echolocation to locate and see objects and creatures. The substance Venber are composed of as many uses one of being used as a powerful super-conductor.

History
The Venber were a primitive race from the frozen moon of Veneba, They were one of the earliest evidence the Andalites obtained of life beyond their own planet at the dawn of Andalite space travel.

However the Venber were discovered by another alien race called The Five. The Five discovered the Venber and began to exploit and harvest the Venber, until the Venber became extinct.

The Yeerks later managed to retrieve Venber DNA from Venbea and used it to genetically recreate them using human DNA. These newly ressurected hybrids were used as guards and labor for the Yeerk's Arctic Kandrona base. Due to their unique physiology Venber were unsuitable hosts, so the Yeerks had microchips put into the head of the new Venbers, making them completely obey the Yeerks.

The Animorphs managed to destroy the Artic base, destroying the Kandrona generator as well as the machines controlling the Venber. Its unknown of the status of these Venber but possible as few still exist wandering the Artic.
