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.
Sea snakes give birth in the ocean to an average of 2â9 young, but as many as 34 may be born. The 54 species in subfamily Hydrophiinae belong to 16 different genera. The six species of sea kraits (genus Laticauda) are not as specialized for aquatic life as the true sea snakes.
