Oncosphere

 

one of the larval stages of most tapeworms. The body is spherical with three pairs of chitinous hooks; hence, an oncosphere is often called a hexacanth—literally, a six-hooked embryo. The oncosphere develops within an egg inside the worm’s uterus. The egg then leaves the body of the host in the host’s feces. The oncosphere continues to develop in water Or in the body of an intermediate host.
