About This Item
Description
Enjoy an up-close-and-personal view of the Insecta Class with these Preserved Grasshoppers (with Tracheal Injection) from Frey Scientific. As insects are the both the largest and most diverse group of animals on earth, these common grasshopper specimens will allow your students to identify the 3 key body regions (head, thorax, and abdomen), 3 pairs of legs (attached to the thorax), the set of antennas on head, mouthparts, and 2 pairs of wings. Plus, these grasshopper specimens have their tracheal injected (the system of air-filled tubes that exchange carbon and dioxide between the grasshopper's tissues and their air) for easier, enhanced identification. Each of these grasshopper specimens measure 3 inches or larger. Sold as pack of 10.Features
