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.
If multiple males are in the same area as a female, they can fight over her, using their strong tails as clubs. Once fertilized and after a period of gestation of about 140 days, a mother gives birth to a single baby. The young are very small, only weighing around 12 ounces and are 6 inches in length. At first, they are extremely vulnerable to predators because their scales are softer and white in color.
