The reconstruction of complete animal life cycles is sometimes a considerable problem, even though the knowledge of the full life cycle may have far-reaching evolutionary implications. A new study published in BMC Biology on artificially induced metamorphosis in an enigmatic crustacean group that was only known from larval stages sheds new light on the evolution of parasitism.
