Pelagic sea snakes dehydrate at sea.
Secondarily marine vertebrates are thought to live independently of fresh water. Here, we demonstrate a paradigm shift for the widely distributed pelagic sea snake, Hydrophis (Pelamis) platurus, which dehydrates at sea and spends a significant part of its life in a dehydrated state corresponding to seasonal drought. Snakes that are captured following prolonged periods without rainfall have lowe...
متن کاملDehydration and drinking responses in a pelagic sea snake.
Recent investigations of water balance in sea snakes demonstrated that amphibious sea kraits (Laticauda spp.) dehydrate in seawater and require fresh water to restore deficits in body water. Here, we report similar findings for Pelamis platurus, a viviparous, pelagic, entirely marine species of hydrophiine ("true") sea snake. We sampled snakes at Golfo de Papagayo, Guanacaste, Costa Rica and de...
متن کاملMechanism of circulatory failure in fresh and sea water drowning.
O LDER concepts as to the cause of death from drowning postulated that spasm of the glottis prevents entry of water into the lungs, that impairment or cessation of the heart beat is due to asphyxia and that use of artificial respiration offers the greatest chance for revival. Recent experimental studies have revealed that this mechanism is dominant in a minority of cases only: 20 per cent in ou...
متن کاملEffects of Iranian Snakes Venom True Sea and Terrestrial Snakes on Some Bacterial Cultures
The antibacterial activities of eight snake crude venom (Macrovipera lebetina obtusa, Pseudocerastes persicus, Pseudocerastes urarachnoides, Echis carinatus sochureki, Gloydius halys caucasicus, Naja (naja) oxiana, and two species of true sea snakes Enhydrina schistose and Hydrophis cyanocinctus) were assessed against five important standard pathogenic bacterial strains (Escherichia coli, ...
متن کاملLibrary Construction from Subnanogram DNA for Pelagic Sea Water and Deep-Sea Sediments
Shotgun metagenomics is a low biased technology for assessing environmental microbial diversity and function. However, the requirement for a sufficient amount of DNA and the contamination of inhibitors in environmental DNA leads to difficulties in constructing a shotgun metagenomic library. We herein examined metagenomic library construction from subnanogram amounts of input environmental DNA f...
