Abstract:The epidermis of a cephalochordate is described by scanning electron microscopy before tail amputation and at the following intervals thereafter: 1 day, 3 days, 6 days, 10 days and 14 days. Before amputation, the epidermis covering the entire body, including the tail, was a monolayer of non‐ciliated cells in a hexagonal array. In one‐day amputees, epidermal cells from the wound edge migrated, evidently by means of contractile lobopodia, forming a loosely associated monolayer on the cut surface. In the three‐da… Show more
