Chicken Footprint Egg

A fanciful descriptor for the eggs of Taenia species—T solium and T saginatum—which have a thick, bile-stained, radially-striated shell that encloses a 6-hooked embryo—oncosphere. Chicken footprint eggs are indistinguishable from each other, from the eggs of Echinococcus granulosus, and from those of other taeniid tapeworms; definitive identification requires that the embryo’s 6 hooks be seen
