Flatworms: planarians (1/5)

A live brown speckled planarian {Dugesia tigrina} feeding on a small piece of Thymus. The planarian's pharynx, a feeding tube that extends from its gastrovascular cavity (digestive tract) tract), is easily visible connecting the mid-section of the worm to the food. These flatworms feed through their pharynx, which is located in the midsection of their body, not on their head. The planarian's auricles and eye spots (ocelli) are planing visible.
