Cover Legend: Coelenterata (Hydromedusae, Acalephae) from Wandtafeln (Wall Charts) by Karl Georg Friedrich Rudolf Leuckart (1822-1898). Leuckart, the "Father of Parasitology" was also a pioneer of 19th century zoology. After earning an M.D. from Gottingen in 1845, he became a Professor of Zoology at Leipzig in 1869. He contributed greatly to the newly established field of animal systematics, dividing Cuvier's Radiata into two new groups: Echinodermata and Coelenterata. In parasitology, Leuckart is best known for studies of vertebrate infections, chiefly tapeworm and trichinosis. Leuckart and von Zenker documented the life cycle of Trichinella spiralis in hogs and men. This led Rudolf Virchow to establish the first meat inspection laws in Germany. Leuckart's Wandtafeln, produced from 1877 to 1892, were used worldwide as teaching aids. Coelenterata, meaning "hollow guts" are essentially a sac with a digestive tract. Numerous tentacles trap their prey and sweep it into the open stoma at the center of the body. Although Coelenterata differ widely in habitat and morphology, they dispose of their victims in similar fashion. In this issue we learn that filoviruses, like Marburg and Ebola, disarm their host by means of glycopeptides first identified in HIV (Implication of a retrovirus-like glycoprotein peptide in the immunopathogenesis of Ebola and Marburg viruses, by Kavitha Yaddanapudi, Gustavo Palacios, Jonathan S. Towner, Ivy Chen, Carlos A. Sariol, Stuart T. Nichol, and W. Ian Lipkin, pages 2519-2530).
