Περιγραφή:Over the past few years an important reduction in the number of nesting marine turtle Caretta caretta individuals has been registered in the Colombian Caribbean, raising the question of a possible extinction in the medium term. A conservation plan is needed. We studied the culture requirements for C. caretta lymphocytes and preliminary karyotype analysis for cytogenetic identifica-tion, immunological study and toxicology without the need to kill individuals. Peripheral blood samples were obtained from 47 individuals in Santa Marta, Colombia and tests were made until optimal conditions were established for lymphocyte culture. The karyotype had 56 chromosomes, 32 macrochromosomes and 24 micro-chromosomes. An ideogram showed that C. caretta has four groups of chromosomes. Sexual chromosomes were not observed. These results do not coincide with the karyotype described from the Pacific (Japan). The present study is the first to include a complete description of the chromosome morphology of turtles from the Atlantic Ocean. it is possible that one of the adaptive strategies of this species is genetic interchange with other species of the family, producing viable hybrids. individuals in this study might be viable hybrids of C. caretta and further molecular studies are needed.
