An aldosterone test measures the level of aldosterone (a hormone made by the adrenal glands), in the blood. Aldosterone helps regulate sodium and potassium levels in the body. This helps control blood pressure and the balance of fluids and electrolytes in the blood. The kidney hormone renin normally stimulates the adrenal glands to release aldosterone.
A seahorse* can have from 100-1500 babies. Averagly 100-200 for most species, but may be as low as 5 for the smaller species, or as high as 1,500. Seahorses can have up to 1500 fry at one time, depending on the species. They are tiny and difficult to raise in captivity.
After the eggs have hatched and the seahorses have fully developed, they will emerge from the male. Unfortunately, the rate of survival is rather low for seahorses and less than one percent will grow into full adults. Seahorses also lack teeth and a proper digestion system, so they eat continuously. Seahorses can grow to be up to eight inches in size. They use their large snouts to inhale food whole.
