After this period, the patient is in a new steady state in which further sodium and water losses do not occur. However, in many patients with diuretic-induced hyponatremia, the disorder first appears after many months of uncomplicated thiazide therapy [5,12].
Out of more than 480 shark species, only three are responsible for a double-digit number of fatal, unprovoked attacks on humans: the great white, tiger, and bull; however, the oceanic whitetip has probably killed many more castaways, not recorded in the statistics.
The great white occupies the top slot on the list of ten most dangerous sharks, with the tiger shark coming in a distant second. The remaining seven species on the 10 most dangerous sharks list, in order of their recorded number of unprovoked lethal and non-lethal attacks over the centuries are: 4. The requiem shark (Carcharhinus spp.*) 5. The sand tiger shark (Carcharias tauruss) 6. The blacktip shark (Carcharhinus limbatus)
