This fortnight we are delving into the peculiar world of caecilians. Fossorial amphibians that seldom show their faces on the surface. We chat about caecilians' strange adaptations and how a ten-year study has shed some light on their reproductive habits. The Species of the Bi-week is a suitably elongated and slimy critter.
