Developing embryos of different species at different stages during the elongation of their posterior body axis, from left to right in developmental time. The labelled regions in red depict a region of undifferentiated cells called the tailbud, with the corresponding region generated from that tissue shaded in grey. Upper row: lamprey; middle row: catshark; bottom row, zebrafish. This figure has been adapted from the following publication: Steventon, B., Duarte, F., Lagadec, R., Mazan, S., Nicolas, J.-F., & Hirsinger, E. (2016). Species tailoured contribution of volumetric growth and tissue convergence to posterior body elongation in vertebrates. Development, 2016. 143(10):1732-41
