Turtle embryos seek sunny side

摘要

Just as adult turtles warm themselves in the midday Sun, turtle embryos 'bask' in their eggs by cosying up to the Sun-warmed side. Wei-Guo Du at the Chinese Academy of Sciences in Beijing and his colleagues shone light through the freshly laid eggs of softshell turtles (Pelodiscus sinensis) to mark the positions of the embryos inside. The team then incubated the eggs, warming them either from above or from one side.
