Moschops
The Moschops is a omnivorous therapsid best known for its love for food. Survivors can train it to favour specific types of food — whether it be Prime Meat or Rare Flowers — and it will become more effective at gathering it. The Moschops is a very cowardly creature and will flee from any sight of danger.

What ARK players use the Moschops for, and how to get the most out of it in ARK: Survival Ascended & Evolved.
