Superworms are much larger than regular mealworms. The scientific name for the Superworm is Zoophobas Mario. Mealworms are classified as Tenebrio molitor. Superworms contain less chitin (the stuff that makes the shells hard) than mealworms, making them easier for your animals to digest.
Superworms are VERY active making them excellent feeders for animals that love to hunt and chase their prey.
