PL-310 HORSESHOE CRAB FLATWORM, Bdelloura candida

These small white triclad flatworms occur on the legs of horseshoe crabs, adhering by glandular caudal adhesive disk. Scraped from the mouth and legs of kicking, scrambling crabs, Bdelloura is ready for a variety of studies. Since it lacks pigment, internal organs are clearly visible through body walls. To demonstrate their keen chemotactic response, the worms may be placed in a vial that opens into a Y-shaped tube with one terminal containing horseshoe crab juice and the other without juice. Invariably, the worms will crawl towards the host fluid. Size: 0.5-1 cm. 1 Dozen
