Abstract

Oxytetracycline when injected intramuscularly produces fluorochrome in bones of the sea-turtle Chelonia mydas (L.). Dosages of from 5-28 mg/kg body weight produced in vivo labels, with no apparent effects on the experimental animals. Brightness of the fluorescence varied with dosage. The label was incorporated rapidly and lasted for 3 yr in the sample. The results are comparable to those from studies performed on mammals, and proffer a useful technique for measuring accretion of hard tissue in herpetological studies-especially for age determination and growth.
