Bone Growth Marks in Tropical Wall Lizard, Hemidactylus brooki

Katti Pancharatna, Suresh M. Kumbar

Abstract


Cross sections of paraffin embedded femurs of various body sized Hemidactylus brooki exhibited 0 – 4 growth marks consisting of lines of arrested growth (LAGs) and growth rings. Femurs of recently hatched lizards showed no such marks. Back calculation indicated that the growth of endosteal layer has not eroded any periosteal LAGs therefore, this lizard may live for a maximum of 4 years in the natural population.

Keywords
