Impact of poxvirus lesions on saltwater crocodile (Crocodylus porosus) skins

Veterinary Microbiology, 2017
Cutaneous poxvirus infections are common in several crocodilian species and are of importance in crocodile farming due to their potential impact on the tanned hide. To confirm poxvirus infection and understand the impact on saltwater crocodile (Crocodylus porosus) skin, fourteen animals from different age groups (five hatchlings, five yearlings and ...

Saltwater crocodile attacks on man

Biological Conservation, 1983
Abstract All instances of attacks on humans by large saltwater crocodiles Crocodylus porosus over a ten-year period are reported. Despite daily human intrusions into the crocodile's aquatic environment and the presence of extremely large male crocodiles (the usual offenders), only four instances of attack occurred in 10 years.

Cryopreservation of saltwater crocodile (Crocodylus porosus) spermatozoa

Reproduction, Fertility and Development, 2017
The aim of the present study was to develop a protocol for the successful cryopreservation of Saltwater crocodile spermatozoa. Sperm cells were frozen above liquid nitrogen vapour in phosphate-buffered saline (PBS) containing either 0.3 M trehalose, 0.3 M raffinose or 0.3 M sucrose and compared with glycerol (0.3–2.7 M).

The assessment of sperm DNA fragmentation in the saltwater crocodile (Crocodylus porosus)

Reproduction, Fertility and Development, 2017
Herein we report a method of assessing DNA fragmentation in the saltwater crocodile using the sperm chromatin dispersion test (SCDt) after including frozen–thawed spermatozoa in a microgel (Halomax; Halotech DNA, Madrid, Spain). Following controlled protein depletion, which included a reducing agent, sperm nuclei with fragmented DNA showed a ...

Saltwater Crocodiles as Tourist Attractions

Journal of Sustainable Tourism, 1998
These study reports the results derived from a pilot research study based on a phenomenographic research approach with 50 respondents in the Northern Territory of Australia. The data permitted a perceptual map to be drawn which identifies tourist fascination with crocodiles as being based on attributes of potential threat, danger, power, links with the

Thyroid Hormone Deiodinases during Embryonic Development of the Saltwater Crocodile (Crocodylus porosus)

General and Comparative Endocrinology, 2002
All tissues of the embryonic saltwater crocodile (Crocodylus porosus) gradually increased in weight during development except for lung tissue, which had a peak weight of 1.09 g at day 67, thereafter decreasing in weight. The brain was a relatively large organ.

Assisted breeding technology in the saltwater crocodile Crocodylus porosus: a review and look to the future

Reproduction, Fertility and Development, 2021
This review reports the current status of artificial breeding technology in the Crocodylia and the future requirements for the establishment of AI in the saltwater crocodile. Although there are challenges regarding safe restraint and immobilisation, semen collection of the saltwater crocodile by manual stimulation has proven effective in yielding ...
