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.
A seahorse has an inefficient digestive system with no stomach, meaning that they need to eat almost constantly. 1  According to The Seahorse Trust, an adult seahorse will eat 30-50 times per day, while baby seahorses eat 3,000 pieces of food per day. A seahorse's neck is well adapted for catching prey, reports Scientific American.
