A pooter is a simple device used in biology and entomology for collecting small arthropods and insects. It typically consists of a small container with a tube attached. The user places one end of the tube in the container and the other end in their mouth to create suction. When the user lightly sucks on the tube, air is drawn through it, causing small insects to be inhaled into the container.
The pooter allows for the gentle collection of specimens without causing harm, making it an effective tool for studying or observing small organisms. It's often used in fieldwork to sample insects from various habitats.
