Healing of Skin Biopsies in Wild Juvenile Green Turtles, Chelonia mydas

Abstract. Skin biopsies are routinely collected from sea turtles for a variety of molecular analyses; however, almost no information exists on the natural healing rates at the site of the biopsy. Here, we monitored the healing rates of 17 juvenile green turtles (Chelonia mydas) for up to 488 d after we took a 6-mm biopsy tissue sample in Eleuthera, The Bahamas. Although scarring persisted for several months, biopsy sampling had a minimal long-term impact—tissue repair and maturation was observed after a year and a half, and there was no evidence of infection at any point during the healing process.
