Zoo Med Can O' Superworms are packed with extra large mealworms (Zophobas morio) are for feeding larger lizard species, box turtles, and aquatic turtle species. These are a farm raised, high-fat and protein snack that can be mixed with other dishes in your pet's food dish. Definitely a hit with bearded dragons, tegus, and turtles! Refrigerate after opening. If your pet does not immediately take to the super worms fresh out of the fridge allow to sit out and warm up before feeding. Not for use on little brothers.
