- Date Issued:
- The author explores the relationship between osmoregulatory problems caused by high salinities near nest sites and the low survival rate of hatchling crocodiles (Crocodylus acutus) in Florida Bay (Everglades National Park, FL). The Na levels of crocodile cloacal fluid was examined, as well as blood plasma. The author also examined the dermal Na permeability. Raw data is presented in tables at the end of the report.

|Summary:||The author explores the relationship between osmoregulatory problems caused by high salinities near nest sites and the low survival rate of hatchling crocodiles (Crocodylus acutus) in Florida Bay (Everglades National Park, FL). The Na levels of crocodile cloacal fluid was examined, as well as blood plasma. The author also examined the dermal Na permeability. Raw data is presented in tables at the end of the report.|
|Summary:||The physiological effects of high salinity on young crocodiles, Crocodylus acutus, was examined in Florida Bay (Everglades National Park) using measurements of electrolyte composition of plasma and cloacal fluid and of possible hatchling food. No final answer can be given to the hypothesis that a major portion of crocodile mortality in Florida Bay is associated with osmoregulatory problems caused by high salinities. Small C. acutus show few physiological specializations for life in saline waters although results indicate that the vicinity of many nest sites are saline enough that difficulties could be encountered in water and salt balance. The author suggests additional studies are needed to establish their mortality under the most stringent salinity.|
