Ossification onset in major skeletal elements in Hippocampus reidi , H. subelongatus and H. zosterae . The scores of 0, 1, 2 and 3 are colour coded as white, yellow, orange and red, respectively. 0, skeletal element is absent (white); 1, element is present but not yet ossified (yellow); 2, element starts to ossify (orange); 3, element is well or fully ossified (red). See text for details. Data for an intra-pouch stage (5.5 mm notochordal length) is given for H. zosterae, this data is from Azzarello [21].
