Cross-sections of Amami rabbit and Japanese hare tibiae showing growth arrest lines (IMAGE)
Caption
Cross-sections of the tibia (shin bone) of the Amami rabbit (left) and the Japanese hare (right), showing multiple growth arrest lines (red) in the Amami rabbit. The presence of many such lines—even in young adults whose bones have just fused—indicates that the Amami rabbit requires several years to reach full maturity.
