Loggerhead Turtles

Loggerhead turtles, Caretta caretta, have been laying eggs in an indoor artificial beach since 1995, at the Port of Nagoya Public Aquarium (PNPA). Two males and four females were mated and those four landed and laid eggs several times during the breeding period in 1996. In 1998 egg laying was observed from April to July and mating was one or two months prior to the nesting season. Blood samples from these individuals were collected monthly in the previously mentioned years in order to investigate the changes in sex steroid hormones (testosterone, estradiol, and progesterone). Moreover, blood chemistry values (total protein, albumin, triglyceride, total cholesterol, total calcium, and inorganic phosphorus) were investigated. In 1998, for the two males, changes in testosterone levels were additionally examined. Blood chemistry values of each turtle changed periodically as sex steroids did based on the breeding period and laying cycle. Data from a completely artificial environment such as the one at the PNPA provide elucidation of the reproductive physiology in these endangered species.

Six adult loggerhead turtles were found stranded and were rescued near Sicily within a period of 12 months. Macroscopically apparent lesions of the shell were present. After thorough physical examination, ketamine-dexmedetomidine-atipamezole induction and tracheal tube insertion all six patients underwent computed tomographic examination under inhalant anaesthesia with isoflurane. A vertebral lesion at the level of the 3<sup>rd</sup> thoracic-lumbar vertebra with vertebral lamina and the vertebral body being involved without compression of the spinal cord, a vertebral lesion at the level of the 7<sup>th</sup> thoracic-lumbar vertebra and a vertebral lesion at the level of the 8<sup>th</sup> thoracic-lumbar vertebra were recorded in the first female. Loss of the shell near the left carapace-plastron bridge, with massive haemorrhage and compression of organs were present in the second female. The remaining four turtles had only superficial lesions with no involvement of bones and organs of the coelom. Computed tomography was proved to be a valuable non-invasive method for clinical examination of stranded sea turtles.
